Detecting photons with superconducting nanowires

Dr. Val Zwiller
Quantum Transport Group, Kavli Institute of Nanoscience Delft, Delft University of Technology

We have developed a new type of single photon detectors based on superconducting nanowires and demonstrate efficient photon detection over a wide spectral range with high time resolution and low dark noise. These detectors have also been recently implemented in near-field experiments where single plasmons were detected. We will discuss the potentials of integrated on chip quantum optics experiments where light emitters, waveguides and detectors are all integrated. In the second part of the talk, the coupling of the emission from a single quantum dot to a Rubidium vapor that was recently achieved in our lab will be discussed and an experiment done with of slow single photons on demand will be presented.
