Exponential suppression of bit-flips in a qubit encoded in an oscillator
Raphaël Lescanne, Marius Villiers, Théau Peronnin +6
A quantum system interacts with its environment, if ever so slightly, no matter how much care is put into isolating it. As a consequence, quantum bits (qubits) undergo errors, putt…
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…
