Protecting Quantum Information in Superconducting Circuits

Explore a conference talk on protecting quantum information in superconducting circuits presented by Michel Devoret from Yale University at the Fred Kavli Special Symposium on Quantum Matter & Quantum Information during the APS March Meeting 2017 in New Orleans. Delve into the fundamental question of prolonging coherence in complex quantum systems beyond their longest-lived components, a crucial step in developing scalable quantum computers. Examine recent experiments testing dynamical protection of logical qubit memory using Josephson circuits and superpositions of coherent states in superconducting resonators. Gain insights into error correction processes and their role in mitigating the effects of qubit-environment coupling.
