| Outline of Final Research Achievements |
In this work, we realized the improvement of performance in superconducting single photon detector (SSPD) such as higher system detection efficiency than 70% at telecommunication wavelength, lower dark count rate than 100 counts/sec, timing jitter of 70ps, and 10 times higher speed operation than before the beggining of this work. We also realized new schemes in quantum information technology by applying SSPD such as quantum interface with 91% fidelity and observation of two photon interferences from independent photon sources.
