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…

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…
