Physics Department Colloquia |
In this talk, I will review how recent progress in the fabrication and control of quantum coherent superconducting circuits has enabled experiments that probe the fundamental physics of quantum measurement. These range from the observation of non-classical weak values to the generation of entanglement through measurement and the tracking of individual quantum trajectories. I will then describe our recent experiments that focus on the special case of spontaneous emission, revealing rich dynamics associated with measurement, and how we are harnessing these dynamics to extend thermodynamics into the regime of single quantum systems.
