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…
Adaptive low-rank approximation and denoised Monte-Carlo approach for high-dimensional Lindblad equations
Claude Le Bris, Pierre Rouchon, Julien Roussel
We present a twofold contribution to the numerical simulation of Lindblad equations. First, an adaptive numerical approach to approximate Lindblad equations using low-rank dynamics…
Convergence and adiabatic elimination for a driven dissipative quantum harmonic oscillator
Rémi Azouit, Alain Sarlette, Pierre Rouchon
We prove that a harmonic oscillator driven by Lindblad dynamics where the typical drive and loss channels are two-photon processes instead of single-photon ones, converges to a pro…
