“He who is good with a hammer thinks everything is a nail.”

- Modified quote from the original by Abraham Maslow

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.

Title:  Testing classical and quantum theory with single photons

Brandon Buonacorsi - Modeling the Exchange Interaction in Silicon Quantum Dots

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

MSc Thesis Presentation

Candidate: Matthew Brown

Speaker: Heather Hoff

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?

Elizabeth Crosson, California Institute of Technology

The equilibrium states of Hamiltonians without a sign problem can in many cases be efficiently sampled using classical Markov chain Monte Carlo methods. These simulation algorithms present a challenge to the possibility of obtaining quantum speedups using transverse-field quantum annealing, and in this talk I'll describe rigorous results on the convergence of simulated quantum annealing to a class of problems that take exponential time to solve by local search.

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.
