TL;DR: A quantum circuit in which an ensemble of electronic spins is coupled to a frequency tunable superconducting resonator and the appearance of a vacuum Rabi splitting in the transmission spectrum of the resonator when its frequency is tuned through the nitrogen-vacancy center electron spin resonance.

TL;DR: In this paper, a transmon circuit with a sample-and-hold detector is presented. But the transmon does not have a high-fidelity single-shot readout, and the readout does not induce extra qubit relaxation.

TL;DR: In this paper, the authors 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 nondestructive single-shot readout.

TL;DR: The intrinsic sensitivity of this detector at frequencies in the 100 kHz-10 MHz range compares favourably with direct-current superconducting quantum interference devices and atomic magnetometers of equivalent spatial resolution, illustrating the potential of artificial quantum systems for sensitive detection and related applications.

TL;DR: Spectroscopic measurements of a superconducting qubit dispersively coupled to a nonlinear resonator driven by a pump microwave field yield a precise characterization of the resonator nonlinearity.
