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…
Convergence of bipartite open quantum systems stabilized by reservoir engineering
Rémi Robin, Pierre Rouchon, Lev-Arcady Sellem
We study a generic family of Lindblad master equations modeling bipartite open quantum systems, where one tries to stabilize a quantum system by carefully designing its interaction…
Quantum control of a cat-qubit with bit-flip times exceeding ten seconds
Ulysse Réglade, Adrien Bocquet, Ronan Gautier +14
Quantum bits (qubits) are prone to several types of errors due to uncontrolled interactions with their environment. Common strategies to correct these errors are based on architect…
Stability and decoherence rates of a GKP qubit protected by dissipation
Lev-Arcady Sellem, Rémi Robin, Philippe Campagne-Ibarcq +1
We analyze an experimentally accessible Lindblad master equation for a quantum harmonic oscillator. It approximately stabilizes finite-energy periodic grid states called Gottesman-…
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…
One hundred second bit-flip time in a two-photon dissipative oscillator
C. Berdou, A. Murani, U. Reglade +19
Current implementations of quantum bits (qubits) continue to undergo too many errors to be scaled into useful quantum machines. An emerging strategy is to encode quantum informatio…
Exponential convergence of a dissipative quantum system towards finite-energy grid states of an oscillator
Lev-Arcady Sellem, Philippe Campagne-Ibarcq, Mazyar Mirrahimi +2
Based on the stabilizer formalism underlying Quantum Error Correction (QEC), the design of an original Lindblad master equation for the density operator of a quantum harmonic oscil…
