Absence of Charge Offset Drift in a Transmon Qubit
Adria Rospars, Hector Hutin, Yannick Seis +8
Superconducting quantum circuits are sensitive to their electrostatic environment: uncontrolled charges accumulating on the electrodes of a Josephson junction shift the energy leve…
Observation and mitigation of microwave echoes from dielectric defects in Josephson traveling wave amplifiers
Matteo Boselli, Joel Grebel, Ambroise Peugeot +3
Amplifying microwave signals with a noise close to the minimum imposed by quantum mechanics is now routinely performed with superconducting quantum devices. In particular, Josephso…
Amplifying microwave pulses with a single qubit engine fueled by quantum measurements
Rémy Dassonneville, Cyril Elouard, Romain Cazali +4
Recent progress in manipulating individual quantum systems enables the exploration of engines exploiting non-classical resources. One of the most appealing is the energy provided b…
Cloaking a qubit in a cavity
Cristóbal Lledó, Rémy Dassonneville, Adrien Moulinas +5
Cavity quantum electrodynamics (QED) uses a cavity to engineer the mode structure of the vacuum electromagnetic field such as to enhance the interaction between light and matter. E…
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…
Transmon-qubit readout using in-situ bifurcation amplification in the mesoscopic regime
R. Dassonneville, T. Ramos, V. Milchakov +8
We demonstrate a transmon qubit readout based on the nonlinear response to a drive of polaritonic meters in-situ coupled to the qubit. Inside a 3D readout cavity, we place a transm…
Propagating Quantum Microwaves: Towards Applications in Communication and Sensing
Mateo Casariego, Emmanuel Zambrini Cruzeiro, Stefano Gherardini +22
The field of propagating quantum microwaves has started to receive considerable attention in the past few years. Motivated at first by the lack of an efficient microwave-to-optical…
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…
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…
Fast high fidelity quantum non-demolition qubit readout via a non-perturbative cross-Kerr coupling
R. Dassonneville, T. Ramos, V. Milchakov +12
Qubit readout is an indispensable element of any quantum information processor. In this work, we experimentally demonstrate a non-perturbative cross-Kerr coupling between a transmo…
