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…
Harnessing two-photon dissipation for enhanced quantum measurement and control
Antoine Marquet, Simon Dupouy, Ulysse Réglade +8
Dissipation engineering offers a powerful tool for quantum technologies. Recently, new superconducting devices have achieved an engineered two-photon dissipation rate exceeding all…
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…
Demonstration of Quantum Advantage in Microwave Quantum Radar
Réouven Assouly, Rémy Dassonneville, Théau Peronnin +2
While quantum entanglement can enhance the performance of several technologies such as computing, sensing and cryptography, its widespread use is hindered by its sensitivity to noi…
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…
Dissipative stabilization of squeezing beyond 3 dB in a microwave mode
R. Dassonneville, R. Assouly, T. Peronnin +3
While a propagating state of light can be generated with arbitrary squeezing by pumping a parametric resonator, the intra-resonator state is limited to 3 dB of squeezing. Here, we…
Number-resolved photocounter for propagating microwave mode
Rémy Dassonneville, Réouven Assouly, Théau Peronnin +2
Detectors of propagating microwave photons have recently been realized using superconducting circuits. However a number-resolved photocounter is still missing. In this letter, we d…
Multiplexed photon number measurement
Antoine Essig, Quentin Ficheux, Théau Peronnin +6
When a two-level system -- a qubit -- is used as a probe of a larger system, it naturally leads to answering a single yes-no question about the system state. Here we propose a meth…
Exponential suppression of bit-flips in a qubit encoded in an oscillator
Raphaël Lescanne, Marius Villiers, Théau Peronnin +6
A quantum system interacts with its environment, if ever so slightly, no matter how much care is put into isolating it. As a consequence, quantum bits (qubits) undergo errors, putt…
Sequential dispersive measurement of a superconducting qubit
Théau Peronnin, Danijela Marković, Quentin Ficheux +1
We present a superconducting device that realizes the sequential measurement of a transmon qubit. The device disables common limitations of dispersive readout such as Purcell effec…
