Bosonic quantum control with a weakly coupled fluxonium qubit
Anaida Ali, Shantanu R. Jha, Shoumik D. Chowdhury +4
Echoed Conditional Displacement (ECD) gates constitute a fundamental building block for quantum control of harmonic oscillator modes. However, bit-flips of the auxiliary qubit rema…

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…

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…
