Collapse and Inversion of the Josephson Potential in a Strongly Driven Superconducting Circuit
Sercan Deve, Marius Villiers, Marijn A. Morssink +2
Superconducting circuits embedding Josephson junctions leverage microwave drives for control and measurement of quantum states. Although increasing the drive power is desirable for…
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…
Cyclically operated Single Microwave Photon Counter with sensitivity
Léo Balembois, Jaime Travesedo, Louis Pallegoix +7
Single photon detection played an important role in the development of quantum optics. Its implementation in the microwave domain is challenging because the photon energy is 5 orde…
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…
