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 continuous…
Unconditionally stable time discretization of Lindblad master equations in infinite dimension using quantum channels
Rémi Robin, Pierre Rouchon, Lev-Arcady Sellem
We examine the time discretization of Lindblad master equations in infinite-dimensional Hilbert spaces. Our study is motivated by the fact that, with unbounded Lindbladian, project…
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…
On encoded quantum gate generation by iterative Lyapunov-based methods
Paulo Sergio Pereira da Silva, Pierre Rouchon
The problem of encoded quantum gate generation is studied in this paper. The idea is to consider a quantum system of higher dimension than the dimension of the quantum…
Benchmarking maximum-likelihood state estimation with an entangled two-cavity state
Valentin Métillon, Stefan Gerlich, Michel Brune +3
The efficient quantum state reconstruction algorithm described in [P. Six et al., Phys. Rev. A 93, 012109 (2016)] is experimentally implemented on the non-local state of two microw…
