PQI June Social Hour

Multiple Speakers
Friday, June 26, 2020 - 2:00pm

Join the PQI Director and Staff for a social hour on Friday, June 26 from 2-3pm (click here to join)!

We'll be using the platform Online Town to host a meet-up in a virtual PQI office. We won't have any food, but come chat and tell us about the trials of the spring semester, your plans for getting back into lab, how PQI could help with anything, the latest video game, or just pop in to casually see who's around. We'll be there.

Anatomy of a Photonic QPU

Eric Johnston
Tuesday, May 19, 2020 - 12:30pm

In building a full-scale QPU, problems of decoherence, scaling, manufacturability, and networking can be solved by using photons as the computational qubits. This also causes some interesting new problems, such as how to wrangle them. Starting with the notation from the Octopus Book, we'll go a bit further, to look at ridiculously-complicated graph states and measurement-based computation. Then we'll go much further, outlining a rough design for a scalable, fault-tolerant photonic QPU.

Coherent nonlinear dynamics and the physics of computation

Hideo Mabuchi
Thursday, June 11, 2020 - 3:30pm

The lecture will be livestreamed from our PQI YouTube channel [click here] and questions from the audience will be collected via the YouTube live channel chat and asked at the end.

Lecture abstract: The Coherent Ising Machine (CIM) is an emerging unconventional computing architecture for non-convex optimization....
