Generation and characterization of a source of wavelength division multiplexing quantum key distribution
Atsushi Yabushita, Takayoshi Kobayashi
Using spontaneous parametric down-conversion, photon pairs entangled in frequency and polarization were generated. After frequency resolving the photon pairs, the polarization corr…
Observation of an oscillatory correlation function of multimode two-photon pairs
Hayato Goto, Yasuo Yanagihara, Haibo Wang +2
An oscillatory correlation function has been observed by the coincidence counting of multimode two-photon pairs produced with a degenerate optical parametric oscillator far below t…
Two-photon interference of multimode two-photon pairs with an unbalanced interferometer
Hayato Goto, Haibo Wang, Tomoyuki Horikiri +2
Two-photon interference of multimode two-photon pairs produced by an optical parametric oscillator has been observed for the first time with an unbalanced interferometer. The time…
Continuous variable teleportation of single photon states (Proceedings version)
Toshiki Ide, Holger F. Hofmann, Takayoshi Kobayashi +1
We investigate the changes to a single photon state caused by the non-maximal entanglement in continuous variable quantum teleportation. It is shown that the teleportation measurem…
Correlations of measurement information and noise in quantum measurements with finite resolution
Holger F. Hofmann, Takayoshi Kobayashi, Akira Furusawa
The original purpose of measurements is to provide us with information about a previously unknown physical property of the system observed. In the Hilbert space formalism of quantu…
