In physical systems composed of many parts, like ultracold atomic ensembles, electrons in a superconductor, or arrays of superconducting circuits, complex dynamics emerges when the different parts of …

In classical mechanics chaos in a dynamical system is related to the unpredictability arising from high sensitivity to the initial configuration. The question of how this behavior, based on the notion…

In April, 2019, the American Physical Society (APS) awarded Regents’ Professor and CQuIC Director, Ivan Deutsch the APS Five Sigma Physicist Award, “a pin awarded to APS members who exhibit outstandin…

A sequence of weak isotropic measurements can yield the optimal measurement of a collection of identical qubits — a POVM over the continuous set of spin-coherent states. We show here a numerical simul…

Xiaodong Qi and Ivan Deutsch celebrated Qi’s Ph.D. completion at the 2018 Commencement ceremony on May 12, 2018.

Strong atom-light coupling is the key to quantum information processing with atoms and photons. It is a common belief that a strong optical field is required to generate a strong atom-light coupling. …

The Jaynes-Cummings model, a widely employed theoretical framework in cavity quantum electrodynamics, is experimentally tested on a platform involving Rydberg-blockaded atomic ensembles. The work open…

The Ivan Deutsch group at CQuIC received a welcome surprise with the publication of an interview with Dr. Deutsch in “Quanta Magazine“. The Deutsch group’s research has focused on the control of a 16-…
