Summary of Research

Quantum computing is a hot field right now. With promises of "quantum supremacy" and the threat of breaking RSA encryption which protects all our computers, it's no surprise why. But is the hype justified? My goal in graduate school (incoming in Fall 2019) is to help shed light on this question. In particular, I hope to look for quantum advantages by first furthering the theory of existing quantum computing devices, especially quantum annealers. This is because current theory often expects a fault-tolerant quantum computer that is not feasible in the near-term. If we're going to find a use from current technology, our search can't begin by assuming we have a perfect device. However, assuming imperfect devices (i.e. non-Markovian noise) quickly leads to analytically unsolvable problems. This is where the power of modern super-computers comes in: we can instead accurately model realistic devices. To summarize, my research goals involve developing accurate computational models of near-term, noisy quantum computing devices and using these models to look for quantum advantages.
