Probing an ensemble of superconducting devices

ORAL

Abstract

We present experimental results on a system in which we use a flux qubit to probe an ensemble of weakly coupled superconducting devices. We employ standard qubit metrology techniques to reveal global device properties. In addition, we discuss the connection with engineered environmental decoherence.
