Dissipative protection of a GKP qubit in a high-impedance superconducting circuit driven by a microwave frequency comb
Lev-Arcady Sellem, Alain Sarlette, Zaki Leghtas +3
We propose a novel approach to generate, protect and control GKP qubits. It employs a microwave frequency comb parametrically modulating a Josephson circuit to enforce a dissipativ…
Manipulating Fock states of a harmonic oscillator while preserving its linearity
Kristinn Juliusson, Simon Bernon, Xin Zhou +7
We present a new scheme for controlling the quantum state of a harmonic oscillator by coupling it to an anharmonic multilevel system (MLS) with first to second excited state transi…
Quantum feedback by discrete quantum non-demolition measurements: towards on-demand generation of photon-number states
I. Dotsenko, M. Mirrahimi, M. Brune +3
We propose a quantum feedback scheme for the preparation and protection of photon number states of light trapped in a high-Q microwave cavity. A quantum non-demolition measurement…
Controllability issues for continuous-spectrum systems and ensemble controllability of Bloch Equations
Karine Beauchard, Jean-Michel Coron, Pierre Rouchon
We study the controllability of the Bloch equation, for an ensemble of non interacting half-spins, in a static magnetic field, with dispersion in the Larmor frequency. This system…
Observer-based Hamiltonian identification for quantum systems
Mazyar Mirrahimi, Pierre Rouchon
An observer-based Hamiltonian identification algorithm for quantum systems is proposed. For the 2-level case an exponential convergence result based on averaging arguments and some…
