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…
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…
Magnifying quantum phase fluctuations with Cooper-pair pairing
W. C. Smith, M. Villiers, A. Marquet +6
Remarkably, complex assemblies of superconducting wires, electrodes, and Josephson junctions are compactly described by a handful of collective phase degrees of freedom that behave…
Dynamics of a qubit while simultaneously monitoring its relaxation and dephasing
Q. Ficheux, S. Jezouin, Z. Leghtas +1
Decoherence originates from the leakage of quantum information into external degrees of freedom. For a qubit the two main decoherence channels are relaxation and dephasing. Here, w…
Coherent oscillations inside a quantum manifold stabilized by dissipation
S. Touzard, A. Grimm, Z. Leghtas +13
Manipulating the state of a logical quantum bit usually comes at the expense of exposing it to decoherence. Fault-tolerant quantum computing tackles this problem by manipulating qu…
Single-photon Resolved Cross-Kerr Interaction for Autonomous Stabilization of Photon-number States
E. T. Holland, B. Vlastakis, R. W. Heeres +8
Quantum states can be stabilized in the presence of intrinsic and environmental losses by either applying active feedback conditioned on an ancillary system or through reservoir en…
