Business in Vancouver discovers nanotechnology

There’ve been two articles in the Vancouver (Canada) newspaper, Business in Vancouver by Tyler Orton about a Simon Fraser University spin-off (start up) company, Nanotech Security. I first mentioned the not-yet-named company in a January 17, 2011 posting about proposed anti-counterfeiting measures based on the structures present on the Blue Morpho butterfly’s wings.

Orton’s Feb. 24, 2015 piece for Business in Vancouver provides an update on the company and on some of the business issues associated with a new technology and the strategy being used to introduce it,

Colour-shifting optical film has been the industry standard for banknote security since the 1990s. Depending on the angle of view, colours change on security features printed on bills in a way that the average person can recognize.

Because the nanotechnology has yet to be fully commercialized, the optical film side of the business is growing the most.

… increased demand for the optical film products prompted Nanotech to add a second shift at its Quebec cellulose facility, which was acquired – along with the legacy business – from North Vancouver’s Fortress Paper (TSX:FTP) in August.

Fortress Paper CEO Chad Wasilenkoff said when discussions began over the sale of Fortress Optical Features (FOF) he was immediately drawn to Nanotech’s butterfly technology.

“Getting a brand-new security feature that has not been used anywhere before … [banks] are just not willing to take a chance on new things in general when it comes to banknotes,” he told Business in Vancouver.

“It will take a little while to come to fruition, but we think putting these two entities [Nanotech and FOF] together will definitely fast-track that.”

Counterfeiting hit its most recent peak in 2004, when 470 fake notes per million were detected across the country, according to a 2011 Bank of Canada (BoC) study.

Wasilenkoff, whose company operates another banknote security firm in Switzerland, said he was happy with the return on investment after Fortress bought the BoC assets for  $750,000 and sold them to Nanotech three years later for $17.5 million.

“We were able to find a solution that was really synergistic for both companies,” he said, adding that Fortress will receive preferential treatment on new security features Nanotech develops.

LeRoux [Nanotech chief development officer Igi LeRoux] added that acquiring the legacy business was necessary if the nanotechnology was to be taken seriously in an industry that greets upstart companies with skepticism.

“[Now] We have an established network, we have an established market base, we have an existing product and – most importantly – we have an existing reputation in the industry.”

Orton’s Aug. 28, 2015 piece for Business in Vancouver builds on his Feb. work (Note: Links have been removed),

Banknotes implanted with nanotechnology, bills printed with pinhead-sized images at maximum resolution or even coins that can store of data.

… it’s not the kind of out-there concepts that only exists in the mind of the CEO of Nanotech Security [Doug Blakeway].

The Burnaby-based banknote security firm has been working non-stop to get these anti-counterfeiting measures onto the streets as quickly as possible and is preparing to ramp up production and sales of its technology after securing $2.6 million in its latest round of fundraising that closed Wednesday (August 26 [2015]).

Blakeway said the plan is to converge the nanotechnology and the optical film technology soon. It’s a measure he said is necessary to introduce the nanotechnology to issuing authorities that may be skeptical about the new product.

It probably won’t be until November before Nanotech discloses which countries are using its technology. Issuing authorities, Blakeway said, are reluctant to reveal exactly what measures they’re taking to fight counterfeiting.

“You can talk about the top 10 issuing authorities or the G8 issuing authorities,” he said.

But Nanotech isn’t stopping only at imprinting bills with the microscopic holes.

Mints began asking last year if it could transfer its technology onto coins in a stamping operation without any extra cost, save for the dye they use.

Moving forward, the coins will be able to store data through an image that’s carried through light waves.

I trust someone will notify the US government about this proposed nanotechnology-enabled coinage. There have been concerns about Canadian coinage in the past as noted in a May 7, 2007 article in thestar.com by Ted Bridis (Associated Press),

An odd-looking Canadian coin with a bright red flower was the culprit behind the U.S. Defence Department’s false espionage warning earlier this year, the Associated Press has learned.

The odd-looking – but harmless – “poppy coin” was so unfamiliar to suspicious U.S. Army contractors travelling in Canada that they filed confidential espionage accounts about them. The worried contractors described the coins as “anomalous” and “filled with something man-made that looked like nano-technology,” according to once-classified U.S. government reports and e-mails obtained by the AP.

The silver-coloured 25-cent piece features the red image of a poppy – Canada’s flower of remembrance – inlaid over a maple leaf. The unorthodox quarter is identical to the coins pictured and described as suspicious in the contractors’ accounts.

The supposed nano-technology actually was a conventional protective coating the Royal Canadian Mint applied to prevent the poppy’s red color from rubbing off. The mint produced nearly 30 million such quarters in 2004 commemorating Canada’s 117,000 war dead.

“It did not appear to be electronic (analog) in nature or have a power source,” wrote one U.S. contractor, who discovered the coin in the cup holder of a rental car. “Under high power microscope, it appeared to be complex consisting of several layers of clear, but different material, with a wire like mesh suspended on top.”

The confidential accounts led to a sensational warning from the Defence Security Service, an agency of the Defence Department, that mysterious coins with radio frequency transmitters were found planted on U.S. contractors with classified security clearances on at least three separate occasions between October 2005 and January 2006 as the contractors travelled through Canada.

It seems those army contractors were prescient about nanotechnology-enabled coins. As for the potential to use these coins for spying, I leave that speculation to those who know more about the technology.

D-Wave passes 1000-qubit barrier

A local (Vancouver, Canada-based, quantum computing company, D-Wave is making quite a splash lately due to a technical breakthrough.  h/t’s Speaking up for Canadian Science for Business in Vancouver article and Nanotechnology Now for Harris & Harris Group press release and Economist article.

A June 22, 2015 article by Tyler Orton for Business in Vancouver describes D-Wave’s latest technical breakthrough,

“This updated processor will allow significantly more complex computational problems to be solved than ever before,” Jeremy Hilton, D-Wave’s vice-president of processor development, wrote in a June 22 [2015] blog entry.

Regular computers use two bits – ones and zeroes – to make calculations, while quantum computers rely on qubits.

Qubits possess a “superposition” that allow it to be one and zero at the same time, meaning it can calculate all possible values in a single operation.

But the algorithm for a full-scale quantum computer requires 8,000 qubits.

A June 23, 2015 Harris & Harris Group press release adds more information about the breakthrough,

Harris & Harris Group, Inc. (Nasdaq: TINY), an investor in transformative companies enabled by disruptive science, notes that its portfolio company, D-Wave Systems, Inc., announced that it has successfully fabricated 1,000 qubit processors that power its quantum computers.  D-Wave’s quantum computer runs a quantum annealing algorithm to find the lowest points, corresponding to optimal or near optimal solutions, in a virtual “energy landscape.”  Every additional qubit doubles the search space of the processor.  At 1,000 qubits, the new processor considers 21000 possibilities simultaneously, a search space which is substantially larger than the 2512 possibilities available to the company’s currently available 512 qubit D-Wave Two. In fact, the new search space contains far more possibilities than there are particles in the observable universe.

A June 22, 2015 D-Wave news release, which originated the technical details about the breakthrough found in the Harris & Harris press release, provides more information along with some marketing hype (hyperbole), Note: Links have been removed,

As the only manufacturer of scalable quantum processors, D-Wave breaks new ground with every succeeding generation it develops. The new processors, comprising over 128,000 Josephson tunnel junctions, are believed to be the most complex superconductor integrated circuits ever successfully yielded. They are fabricated in part at D-Wave’s facilities in Palo Alto, CA and at Cypress Semiconductor’s wafer foundry located in Bloomington, Minnesota.

“Temperature, noise, and precision all play a profound role in how well quantum processors solve problems.  Beyond scaling up the technology by doubling the number of qubits, we also achieved key technology advances prioritized around their impact on performance,” said Jeremy Hilton, D-Wave vice president, processor development. “We expect to release benchmarking data that demonstrate new levels of performance later this year.”

The 1000-qubit milestone is the result of intensive research and development by D-Wave and reflects a triumph over a variety of design challenges aimed at enhancing performance and boosting solution quality. Beyond the much larger number of qubits, other significant innovations include:

  •  Lower Operating Temperature: While the previous generation processor ran at a temperature close to absolute zero, the new processor runs 40% colder. The lower operating temperature enhances the importance of quantum effects, which increases the ability to discriminate the best result from a collection of good candidates.​
  • Reduced Noise: Through a combination of improved design, architectural enhancements and materials changes, noise levels have been reduced by 50% in comparison to the previous generation. The lower noise environment enhances problem-solving performance while boosting reliability and stability.
  • Increased Control Circuitry Precision: In the testing to date, the increased precision coupled with the noise reduction has demonstrated improved precision by up to 40%. To accomplish both while also improving manufacturing yield is a significant achievement.
  • Advanced Fabrication:  The new processors comprise over 128,000 Josephson junctions (tunnel junctions with superconducting electrodes) in a 6-metal layer planar process with 0.25μm features, believed to be the most complex superconductor integrated circuits ever built.
  • New Modes of Use: The new technology expands the boundaries of ways to exploit quantum resources.  In addition to performing discrete optimization like its predecessor, firmware and software upgrades will make it easier to use the system for sampling applications.

“Breaking the 1000 qubit barrier marks the culmination of years of research and development by our scientists, engineers and manufacturing team,” said D-Wave CEO Vern Brownell. “It is a critical step toward bringing the promise of quantum computing to bear on some of the most challenging technical, commercial, scientific, and national defense problems that organizations face.”

A June 20, 2015 article in The Economist notes there is now commercial interest as it provides good introductory information about quantum computing. The article includes an analysis of various research efforts in Canada (they mention D-Wave), the US, and the UK. These excerpts don’t do justice to the article but will hopefully whet your appetite or provide an overview for anyone with limited time,

A COMPUTER proceeds one step at a time. At any particular moment, each of its bits—the binary digits it adds and subtracts to arrive at its conclusions—has a single, definite value: zero or one. At that moment the machine is in just one state, a particular mixture of zeros and ones. It can therefore perform only one calculation next. This puts a limit on its power. To increase that power, you have to make it work faster.

But bits do not exist in the abstract. Each depends for its reality on the physical state of part of the computer’s processor or memory. And physical states, at the quantum level, are not as clear-cut as classical physics pretends. That leaves engineers a bit of wriggle room. By exploiting certain quantum effects they can create bits, known as qubits, that do not have a definite value, thus overcoming classical computing’s limits.

… The biggest question is what the qubits themselves should be made from.

A qubit needs a physical system with two opposite quantum states, such as the direction of spin of an electron orbiting an atomic nucleus. Several things which can do the job exist, and each has its fans. Some suggest nitrogen atoms trapped in the crystal lattices of diamonds. Calcium ions held in the grip of magnetic fields are another favourite. So are the photons of which light is composed (in this case the qubit would be stored in the plane of polarisation). And quasiparticles, which are vibrations in matter that behave like real subatomic particles, also have a following.

The leading candidate at the moment, though, is to use a superconductor in which the qubit is either the direction of a circulating current, or the presence or absence of an electric charge. Both Google and IBM are banking on this approach. It has the advantage that superconducting qubits can be arranged on semiconductor chips of the sort used in existing computers. That, the two firms think, should make them easier to commercialise.

Google is also collaborating with D-Wave of Vancouver, Canada, which sells what it calls quantum annealers. The field’s practitioners took much convincing that these devices really do exploit the quantum advantage, and in any case they are limited to a narrower set of problems—such as searching for images similar to a reference image. But such searches are just the type of application of interest to Google. In 2013, in collaboration with NASA and USRA, a research consortium, the firm bought a D-Wave machine in order to put it through its paces. Hartmut Neven, director of engineering at Google Research, is guarded about what his team has found, but he believes D-Wave’s approach is best suited to calculations involving fewer qubits, while Dr Martinis and his colleagues build devices with more.

It’s not clear to me if the writers at The Economist were aware of  D-Wave’s latest breakthrough at the time of writing but I think not. In any event, they (The Economist writers) have included a provocative tidbit about quantum encryption,

Documents released by Edward Snowden, a whistleblower, revealed that the Penetrating Hard Targets programme of America’s National Security Agency was actively researching “if, and how, a cryptologically useful quantum computer can be built”. In May IARPA [Intellligence Advanced Research Projects Agency], the American government’s intelligence-research arm, issued a call for partners in its Logical Qubits programme, to make robust, error-free qubits. In April, meanwhile, Tanja Lange and Daniel Bernstein of Eindhoven University of Technology, in the Netherlands, announced PQCRYPTO, a programme to advance and standardise “post-quantum cryptography”. They are concerned that encrypted communications captured now could be subjected to quantum cracking in the future. That means strong pre-emptive encryption is needed immediately.

I encourage you to read the Economist article.

Two final comments. (1) The latest piece, prior to this one, about D-Wave was in a Feb. 6, 2015 posting about then new investment into the company. (2) A Canadian effort in the field of quantum cryptography was mentioned in a May 11, 2015 posting (scroll down about 50% of the way) featuring a profile of Raymond Laflamme, at the University of Waterloo’s Institute of Quantum Computing in the context of an announcement about science media initiative Research2Reality.

Medical isotope team at TRIUMF (Canada’s national laboratory for particle and nuclear physics) wins award

I’ve written a few times about the development of a new means for producing medical isotopes that does not require nuclear materials. (my June 10, 2014 posting and my June 9, 2013 posting,) The breakthrough was made at TRIUMF, Canada’s national laboratory for particle and nuclear physics, which is located in Vancouver, and the team which made the breakthrough is being honoured. From a Feb. 17, 2015 TRIUMF news release,

For their outstanding teamwork in realizing a solution for safe and reliable isotope production for hospitals in Canada,interdisciplinary research team CycloMed99 will be receiving a prestigious national award at a ceremony in Ottawa today [Feb. 17, 2015]. The Honourable David Johnston, Governor General of Canada, will present the NSERC  [Natural Sciences and Engineering Research Council of Canada] Brockhouse Canada Prize for Interdisciplinary Research in Science and Engineering to the team in recognition of their seamless teamwork and successes.

Drawing from expertise in physics, chemistry, and nuclear medicine, the team set out five years ago to develop a reliable, alternative means of production for a key medical isotope in order to eliminate the threat of a supply shortage – a catastrophic healthcare crisis for patients around the world. Technetium-99m (Tc-99m) is the world standard for medical imaging to diagnose cancer and heart disease. Every day, 5,000 medical procedures in
Canada and 70,000 daily worldwide depend on this isotope. With funding support from NSERC, CIHR and Natural Resources Canada, the team developed technology that uses medical cyclotrons already installed and operational in major hospitals across Canada to produce enough Tc-99m on a daily basis.

This innovation is safer and more environmentally friendly than current technology because it eliminates the need for highly enriched uranium, also avoiding the generation
of highly radioactive waste. Canada’s healthcare system would save money by producing isotopes locally under a full-cost recovery model.

The project resulted in over a dozen scientific publications, several provisional patents and a training opportunity for more than 175 individuals.

Now, the research team is focused on working with the world’s major cyclotron manufacturers to add factory-supported Tc-99m production capability to their existing product lines so the technology will become standard in future machines.

CycloMed99 is also working with a Canadian start-up company to license, transfer and sell this technology around the world. This will allow hospitals and companies with cyclotrons to retrofit their existing infrastructure with a Made in Canada solution to produce this valuable material.

Congratulations to the CycloMed99 team, recipients of the Brockhouse Canada Prize:

• Dr. Paul Schaffer, a chemist by training and Division Head, Nuclear Medicine at TRIUMF; Adjunct Professor, Dept. of Chemistry at Simon Fraser University; and Professor, Dept. of Radiology at the University of British Columbia (UBC);
