High-gain weakly nonlinear flux-modulated Josephson parametric amplifier using a SQUID-array
X. Zhou, V. Schmitt, P. Bertet +4
We have developed and measured a high-gain quantum-limited microwave parametric amplifier based on a superconducting lumped LC resonator with the inductor L including an array of 8…
Characterization of a two-transmon processor with individual single-shot qubit readout
A. Dewes, F. R. Ong, V. Schmitt +5
We report the characterization of a two-qubit processor implemented with two capacitively coupled tunable superconducting qubits of the transmon type, each qubit having its own non…
The Bright Side of Coulomb Blockade
Max Hofheinz, Fabien Portier, Quentin Baudouin +5
We explore the photonic (bright) side of dynamical Coulomb blockade (DCB) by measuring the radiation emitted by a dc voltage-biased Josephson junction embedded in a microwave reson…
Strong Coupling of a Spin Ensemble to a Superconducting Resonator
Y. Kubo, F. R. Ong, P. Bertet +11
We report the realization of a quantum circuit in which an ensemble of electronic spins is coupled to a frequency tunable superconducting resonator. The spins are Nitrogen-Vacancy…
NMR-like control of a quantum bit superconducting circuit
E. Collin, G. Ithier, A. Aassime +3
Different nanofabricated superconducting circuits based on Josephson junctions have already achieved a degree of quantum coherence sufficient to demonstrate coherent superpositions…
Density of states in a superconductor carrying a supercurrent
A. Anthore, H. Pothier, D. Esteve
We have measured the tunneling density of states (DOS) in a superconductor carrying a supercurrent or exposed to an external magnetic field. The pair correlations are weakened by t…
