Quantum Complexity: Theory and Application (Dagstuhl Seminar 21261)

Abstract

This report documents the program and outcomes of Dagstuhl Seminar 21261 “Quantum Complexity: Theory and Application”. The seminar ran from June 27 to July 2 , 2021, and was held in a hybrid format (due to COVID travel restrictions). Of the 55 total participants from 14 countries, 17 participants were on-site, and 38 were remote. Recent advances in both theoretic and experimental aspects of quantum complexity theory were presented and discussed, ranging from new theoretical developments via a “Quantum Strong Exponential Time Hypothesis”, to more experimentally oriented talks involving benchmarking of random circuits in quantum supremacy experiments. In addition, an open problem session and a discussion session regarding the current state of the field were included.
