Dynamics of a qubit while simultaneously monitoring its relaxation and dephasing

Q Ficheux, S Jezouin, Z Leghtas, B Huard - Nature communications, 2018 - nature.com
Decoherence originates from the leakage of quantum information into external degrees of
freedom. For a qubit, the two main decoherence channels are relaxation and dephasing …

monochromatic field modes. It allows for multiple simultaneous measurements of arbitrarily …

Characterizing a statistical arrow of time in quantum measurement dynamics

PM Harrington, D Tan, M Naghiloo, KW Murch - Physical Review Letters, 2019 - APS
