High-sensitivity AC-charge detection with a MHz-frequency fluxonium qubit
B. -L. Najera-Santos, R. Rousseau, K. Gerashchenko +15
Owing to their strong dipole moment and long coherence times, superconducting qubits have demonstrated remarkable success in hybrid quantum circuits. However, most qubit architectu…
Robust sparse IQP sampling in constant depth
Louis Paletta, Anthony Leverrier, Alain Sarlette +2
Between NISQ (noisy intermediate scale quantum) approaches without any proof of robust quantum advantage and fully fault-tolerant quantum computation, we propose a scheme to achiev…
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…
Stabilization of approximate GHZ state with quasi-local couplings
Vincent Martin, Alain Sarlette
We propose a reservoir design, composed of fixed dissipation operators acting each on few local subsystems, to stabilize an approximate GHZ state on n qubits. The main idea is to w…
Complete positivity violation of the reduced dynamics in higher-order quantum adiabatic elimination
Masaaki Tokieda, Cyril Elouard, Alain Sarlette +1
This paper discusses quantum adiabatic elimination, which is a model reduction technique for a composite Lindblad system consisting of a fast decaying sub-system coupled to another…
Designing High-Fidelity Zeno Gates for Dissipative Cat Qubits
Ronan Gautier, Mazyar Mirrahimi, Alain Sarlette
Bosonic cat qubits stabilized with a driven two-photon dissipation are systems with exponentially biased noise, opening the door to low-overhead, fault-tolerant and universal quant…
