ONLINE Special Colloquium - Manuel Endres | Institute for Quantum Information and Matter, Caltech

MCQST Colloquium Münchner Physik-Kolloquium

Address / Location


The MCQST Colloquium Series features interdisciplinary talks given by visiting international speakers. The monthly colloquial covers topics spanning all MCQST research units and are available to audiences worldwide. The main goal of the series is to create the framework for idea exchange, to strengthen links with QST leading groups worldwide, as well as to act as an integral part of the local educational environment.

On 5 October 2020 we are excited to invite you to the special colloquim by Manuel Endres, Assistant Professor at the Institute for Quantum Information and Matter at Caltech.This special edition colloquia is organised jointly by the Münchner Physik-Kolloquium and MCQST.


Quantum Science with Tweezer Arrays

Optical tweezer arrays applied to cold neutral atoms have emerged as a versatile platform for quantum science. In particular, atom-by-atom assembly—a feedback-based scheme for entropy removal—now enables the generation of defect-free atomic arrays with flexible geometric arrangements. These assembled atomic arrays form the starting point for experiments in quantum simulation and computing based on excitation to Rydberg states. I will review these developments and describe our very recent results for alkaline-earth atoms. The rich level structure of such two valence-electron atoms enables novel cooling, control, and read-out schemes. We have used these techniques in demonstrations of record imaging and two-qubit entanglement fidelities for neutral atoms. At the same time, this direction naturally merges high-precision spectroscopy with single-atom control within many-atom systems, as exemplified by novel ‘tweezer array clocks’. All in all, tweezer arrays with alkali or alkaline-earth atoms promise a host of high-fidelity applications along almost all axes of quantum science, including simulation, computing, metrology, and communication.
