Observation of a power transfer controlled by the phase of a quantum superposition
Nathanaël Cottet, Sébastien Jezouin, Bogdan Reznychenko +2
A driven qubit exchanges energy with the propagating modes that drive it. When two spatially separated modes drive a single qubit with opposite amplitudes, their net action on the…
Robust quantum communication through lossy microwave links
James D. Teoh, Nathanael Cottet, Patrick Winkel +3
Entanglement generation lies at the heart of many quantum networking protocols as it enables distributed and modular quantum computing. For superconducting qubits, entanglement fid…
Enhancing dissipative cat qubit protection by squeezing
Rémi Rousseau, Diego Ruiz, Emanuele Albertinale +38
Dissipative cat-qubits are a promising architecture for quantum processors due to their built-in quantum error correction. By leveraging two-photon stabilization, they achieve an e…
Autoparametric resonance extending the bit-flip time of a cat qubit up to 0.3 s
Antoine Marquet, Antoine Essig, Joachim Cohen +9
Cat qubits, for which logical and are coherent states of a harmonic mode, offer a promising route towards quantum error correction. Using dis…
Energetics of a Single Qubit Gate
Jeremy Stevens, Daniel Szombati, Maria Maffei +10
Qubits are physical, a quantum gate thus not only acts on the information carried by the qubit but also on its energy. What is then the corresponding flow of energy between the qub…
Maxwell's demon in superconducting circuits
Nathanaël Cottet, Benjamin Huard
This paper provides an overview of the first experimental realizations of quantum-mechanical Maxwell's demons based on superconducting circuits. The principal results of these expe…
Observing a quantum Maxwell demon at work
N. Cottet, S. Jezouin, L. Bretheau +7
In apparent contradiction to the laws of thermodynamics, Maxwell's demon is able to cyclically extract work from a system in contact with a thermal bath exploiting the information…
Using Spontaneous Emission of a Qubit as a Resource for Feedback Control
P. Campagne-Ibarcq, S. Jezouin, N. Cottet +6
Persistent control of a transmon qubit is performed by a feedback protocol based on continuous heterodyne measurement of its fluorescence. By driving the qubit and cavity with micr…
