Quantum state tomography with non-instantaneous measurements, imperfections and decoherence
Pierre Six, Philippe Campagne-Ibarcq, Igor Dotsenko +3
Tomography of a quantum state is usually based on positive operator-valued measure (POVM) and on their experimental statistics. Among the available reconstructions, the maximum-lik…
Anatomy of Fluorescence: Quantum trajectory statistics from continuously measuring spontaneous emission
Andrew N. Jordan, Areeya Chantasri, Pierre Rouchon +1
We investigate the continuous quantum measurement of a superconducting qubit undergoing fluorescence. The fluorescence of the qubit is detected via a phase-preserving heterodyne me…
Observing quantum state diffusion by heterodyne detection of fluorescence
P. Campagne-Ibarcq, P. Six, L. Bretheau +4
A qubit can relax by fluorescence, which prompts the release of a photon into its electromagnetic environment. By counting the emitted photons, discrete quantum jumps of the qubit…
Quantum dynamics of an electromagnetic mode that cannot contain N photons
Landry Bretheau, Philippe Campagne-Ibarcq, Emmanuel Flurin +2
Electromagnetic modes are instrumental in building quantum machines. In this experiment, we introduce a method to manipulate these modes by effectively controlling their phase spac…
