Quantum Simulation of Hyperbolic Space with Circuit Quantum Electrodynamics

December 7, 2020 - 11:30am
Igor Boettcher
JQI postdoc seminar

Looking for some fresh bathroom tiles? Why don't you try regular 7-gons this time, it looks amazing! Only requirement: You'd need to live in hyperbolic space of constant negative curvature. To see how this would be like, let me take you onto a journey into hyperbolic space through recent breakthrough experiments in circuit quantum electrodynamics, where such tilings are realized with superconducting resonators and photons are tricked into believing that space is hyperbolic. I will show how these finite lattice geometries can be mapped onto quantum field theories in continuous negatively curved space and how this can be used to compute observables relevant for experiments.

We are hosting the Fall 2020 JQI Seminars virtually as Zoom meetings. JQI members and affiliates will receive a Zoom link in an email announcing each seminar. For those without access to Zoom, we will also be live streaming each seminar on YouTube. Once a seminar starts, you will find a link to the live stream on our YouTube page at
