Quantum interference of heat and thermalization in superconducting circuits
ORAL · Invited
Abstract
Superconducting circuits combined with engineered heat baths form a basis to investigate quantum thermodynamics on a chip [1]. I will present our experimental work on bolometric detection of quantum interference in such a system. We consider a driven system composed of a strongly coupled qubit and a cavity [2]. As a second topic, I introduce ideas of thermalization in isolated quantum circuits [3,4,5].
