General Physics Colloquium, Prof. Peter McMahon, A&EP, Cornell University.

Refreshments from 3:30-3:50 pm.

Title:  Explorations in computation using classical and quantum photonics

Host:  Carl Franck

Abstract:  In this colloquium I will discuss some of the main open challenges and opportunities in both classical and quantum computing, and how the work we have started to do in my newly formed lab at Cornell relates to both. In the space of quantum computing, I will first provide a very brief overview of the state of the field. I will then cover some of the physical-implementation challenges as well as provide a glimpse of the hunt for useful applications of near-term quantum computers, including in quantum simulation and in machine learning. In the space of unconventional classical computing, I will focus on the resurgence of interest in photonic computers, describing how optics could deliver benefits over electronics, and how we might harness the fundamental strengths of optics to build special-purpose computers that are orders of magnitude more energy-efficient than even carefully engineered, custom electronic processors, such as Google’s Tensor Processing Unit.
