I will introduce quantum annealing as a technique for harnessing quantum mechanics to solve hard problems. The design of a quantum annealing processor based on superconducting flux qubits, some of the challenges we have encountered in constructing it, and measurements confirming the role of quantum mechanics in such processors will be presented. Finally, I will briefly discuss recent benchmarking and simulation results using the D-Wave 2000Q processor.

How does one sell security? How does one commercialize such nebulous concepts such as “Trust”, “Security” and “Cryptography”? Cryptography, which is just one building block of security, is based on other more abstract building blocks such as algorithms which have a foundation on hard mathematical problems.
CryptoWorks21 at the University of Waterloo, together with representatives from the Standards Council of Canada (SCC) and the European Telecommunications Standards Institute (ETSI), are proud to present a lunch-time standards session.

Title: Testing classical and quantum theory with single photons
Silicon metal-oxide-semiconductor field effect transistor (MOSFET) quantum dots are promising candidates for scalable quantum computing using electron spin qubits due to their long coherence times, compact size, and ease of integration into existing fabrication technologies. I will introduce how we fabricate these devices and describe the experimental characterizations we do to check the stability and tunability of our quantum dots. In a double quantum dot device, two qubit gates are realized

Abstract: Software is a key asset of any new business. How do you protect the results of weeks or months of hard labour? Who owns the software and how do I mange its development to ensure its inherent value is maintained? Should I use Open Source, or even contribute to Open Source? What are the benefits and how does this measure up against the risks?
Tarun Patel: Photocurrent imaging of charge density wave transitions in ultrathin 1T-TaS2 1T-TaS2 is a layered van-der Waals material which shows multiple charge density wave (CDW) transitions as a function of temperature. Ultrathin flakes fabricated by mechanical exfoliation and protected from oxidation with h-BN capping in inert atmosphere have been shown to retain these transitions.
The quantum anomalous Hall (QAH) effect is a quantum Hall effect induced by spontaneous magnetization instead of an external magnetic field. The effect occurs in two-dimensional (2D) insulators with topologically nontrivial electronic band structure which is characterized by a non-zero Chern number. The experimental observation of the QAH effect in thin films of magnetically doped (Bi,Sb)2Te3 topological insulators (TIs) paves the way for practical applications of dissipationless quantum Hall edge states.
