Quantum Optics Seminar by Dr. Naoto Namekata

In the past decade, we have developed photon detectors at a telecommunication wavelength. Performances of the photon detectors have considerably progressed, and they now enable us to realize quantum communications, especially the fiber-optic quantum key distribution. Recently, the photon detector has been able to obtain the photon number resolution with high detection efficiency.Therefore, optical quantum state engineering is up to multi-photon level. In this talk, I will review the recent progress of the photon detection technologies and show the some experimental researchs using  them, i.e. the quantum key distribution, the Schrodinger's kitten state generation, and the plasmonics in quantum regeme.
