IFISC Seminar on Wednesday Mar 02, 2022 at 14:30 Place: Zoom Seminar Title: Benchmarking experimental quantum computation: rigorous noise analysis in the simulation of dissipative collective effects Speaker: Marco Cattaneo, IFISC and University of Helsinki Abstract: <p>&nbsp;In the era of near-term quantum computers, understanding the features of noise in quantum devices is essential to benchmark and improve the accuracy of quantum simulation algorithms. Here, we present an in-depth comparison between the results of a rigorous noise analysis of a near-term quantum computer and the outcomes of the &nbsp;first fully quantum experimental simulation of dissipative collective effects, the relevance of which ranges from the study of entanglement in biological systems to the engineering of dissipative phase transitions and quantum synchronization. We show that the conclusions drawn from the noise analysis crucially improve our understanding of the dynamics we are actually implementing on the quantum computer, and that the widely employed randomized benchmarking procedure may not always be reliable to detect faulty gates in the algorithm.</p> <p>Zoom:&nbsp;<a href="https://us02web.zoom.us/j/83829318876?pwd=Z2pqbUtIMEV3NUQvU0hpakp0NGtsUT09">https://us02web.zoom.us/j/83829318876?pwd=Z2pqbUtIMEV3NUQvU0hpakp0NGtsUT09</a></p>; Url event:https://ifisc.uib-csic.es/en/events/seminars/benchmarking-experimental-quant...
