Description

Artificial atoms based on superconducting qubits can be used to perform quantum non-demolition measurements of signal photons in microwave cavity detectors of low mass dark matter waves. By measuring only the photon wave's amplitude while remaining insensitive to the conjugate phase observable, these sensors evade the Heisenberg uncertainty principle and exhibit noise levels far below those of standard quantum-limited amplifiers. The low dark count rate of this novel sensor technology will enable future background-free experiments searching for axions and hidden photons at higher masses in the 10-20 GHz range.
