Exponential stabilization of quantum systems under continuous non-demolition measurements
Gerardo Cardona, Alain Sarlette, Pierre Rouchon
We present a novel continuous-time control strategy to exponentially stabilize an eigenstate of a Quantum Non-Demolition (QND) measurement operator. In open-loop, the system conver…

Continuous-time Quantum Error Correction with Noise-assisted Quantum Feedback
Gerardo Cardona, Alain Sarlette, Pierre Rouchon
We address the standard quantum error correction using the three-qubit bit-flip code, yet in continuous-time. This entails rendering a target manifold of quantum states globally at…

Exponential stochastic stabilization of a two-level quantum system via strict Lyapunov control
Gerardo Cardona, Alain Sarlette, Pierre Rouchon
This article provides a novel continuous-time state feedback control strategy to stabilize an eigenstate of the Hermitian measurement operator of a two-level quantum system. In ope…
