High-performance repetition cat code using fast noisy operations
Francois-Marie Le Régent, Camille Berdou, Zaki Leghtas +2
Bosonic cat qubits stabilized by two-photon driven dissipation benefit from exponential suppression of bit-flip errors and an extensive set of gates preserving this protection. The…
Dynamically enhancing qubit-photon interactions with anti-squeezing
M. Villiers, W. C. Smith, A. Petrescu +7
The interaction strength of an oscillator to a qubit grows with the oscillator's vacuum field fluctuations. The well known degenerate parametric oscillator has revived interest in…
Two-photon driven Kerr quantum oscillator with multiple spectral degeneracies
Diego Ruiz, Ronan Gautier, Jérémie Guillaud +1
Kerr nonlinear oscillators driven by a two-photon process are promising systems to encode quantum information and to ensure a hardware-efficient scaling towards fault-tolerant quan…
Structurally stable subharmonic regime of a driven quantum Josephson circuit
Michiel Burgelman, Pierre Rouchon, Alain Sarlette +1
Driven quantum nonlinear oscillators, while essential for quantum technologies, are generally prone to complex chaotic dynamics that fall beyond the reach of perturbative analysis.…
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…
