Real-time quantum state estimation in circuit QED via the Bayesian approach

Yang Yang, Beili Gong, Wei Cui

Using a superconducting circuit QED device, we present a theoretical study of real-time quantum state estimation via the quantum Bayesian approach. Suitable conditions under which the quantum Bayesian approach can accurately update the density matrix of the qubit are analyzed. We also consider the correlation between some basic and physically meaningful parameters of the circuit QED and the performance of the Bayesian approach. Our results advance the understanding of the quantum Bayesian approach.

Atomic decay rates in a dielectric medium: a test of the standard QED Hamiltonian

Seng‐Tiong Ho, Prem Kumar

Recently, there has been great experimental interest in studying the behavior of active atoms embedded in a dielectric medium because of the possibility of manipulating the spontaneous decay rate of these atoms.1 More important, the decay rate of such atoms warrants special study as it is affected by additional physical factors not present in cavity QED. We show that the usual value given for one of these additional factors is incorrect, and the correct value can be related to a basic property of the standard QED Hamiltonian.
