Stabilization of finite-energy grid states of a quantum harmonic oscillator by reservoir engineering with two dissipation channels
Rémi Robin, Pierre Rouchon, Lev-Arcady Sellem
We propose and analyze an experimentally accessible Lindblad master equation for a quantum harmonic oscillator, simplifying a previous proposal to alleviate implementation constrai…
Diffusive Stochastic Master Equation (SME) with dispersive qubit/cavity coupling
Pierre Rouchon
A detailed analysis of the quantum diffusive Stochastic Master Equation (SME) for qubit/cavity systems with dispersive coupling is provided. This analysis incorporates classical in…
Confinement to deterministic manifolds and low-dimensional solution formulas for continuously measured quantum systems
Alain Sarlette, Cyril Elouard, Pierre Rouchon
Quantum systems subjected to a continuous weak measurement process evolve according to stochastic differential equations (SDE). Depending on the outcomes of these stochastic measur…
Time-averaged continuous quantum measurement
Pierre Guilmin, Pierre Rouchon, Antoine Tilloy
The theory of continuous quantum measurement allows to reconstruct the state of a system from a continuous stochastic measurement record . However, this truly continuou…
Monitoring the energy of a cavity by observing the emission of a repeatedly excited qubit
Hector Hutin, Antoine Essig, Réouven Assouly +3
The number of excitations in a large quantum system (harmonic oscillator or qudit) can be measured in a quantum nondemolition manner using a dispersively coupled qubit. It typicall…
Convergence of bipartite open quantum systems stabilized by reservoir engineering
Rémi Robin, Pierre Rouchon, Lev-Arcady Sellem
We study a generic family of Lindblad master equations modeling bipartite open quantum systems, where one tries to stabilize a quantum system by carefully designing its interaction…
