Search Talks

In this talk I will give updates on two projects: Firstly, Perimeter and Two Small Fish Ventures are currently supporting a group of five PSI alumni in writing a play themed around quantum science & technology, with the goal of enriching public discourse on these fields. On the one hand, we aim to inform the audience about key quantum concepts in an entertaining setting. On the other hand, we are exploring questions such as "Will we really have fault-tolerant quantum computers in five years? Which quantum research is better pursued in industry vs. academia? Who will benefit from commercialization? What drives scientists to do quantum research - for scientific understanding, or because 'today's theoretical physics is tomorrow's technology'?". Five characters debate different takes on these questions in a Douglas-Adams-inspired sci-fi setting.

Secondly, I will review recent developments in classical and quantum reservoir computing.

The remnant of a binary black hole coalescence is a perturbed black hole, which equilibrates by emitting ringdown gravitational waves. These ringdown waves not only encode information in their frequencies about the spacetime structure of the remnant black hole metric, but also have imprints in their amplitudes of the progenitor black hole binary's properties. In this talk I will highlight recent results in black hole ringdown data analysis and new understanding of astrophysical ringdown amplitudes gleaned from numerical relativity simulations, and will then discuss how ringdown analyses may become a vital tool for making inferences of binary black hole properties - even in situations where the gravitational wave signal from the binary inspiral itself is never directly observed.
