Tomography and state reconstruction with superconducting single-photon detectors
arXiv:1206.5145 · doi:10.1103/PhysRevA.86.062113
Abstract
We perform quantum state reconstruction of coherent and thermal states with a detector which has an enhanced multiphoton response. The detector is based on superconducting nanowires, where the bias current sets the dependence of the click probability on the photon number; this bias current is used as tuning parameter in the state reconstruction. The nonlinear response makes our nanowire-based detector superior to the linear detectors that are conventionally used for quantum state reconstruction.
