Conditional transfer of quantum correlation in the intensity of twin beams
Yun Zhang, Kazuhiro Hayasaka, Katsuyuki Kasai
A conditional protocol of transferring quantum-correlation in continuous variable regime was experimentally demonstrated. The quantum-correlation in two pairs of twin beams, each c…
Generation of twin beams from an optical parametric oscillator pumped by a frequency-doubled diode laser
Kazuhiro Hayasaka, Yun Zhang, Katsuyuki Kasai
Quantum-correlated twin beams were generated from a triply resonant optical parametric oscillator with an a-cut KTP crystal pumped by a frequency-doubled diode laser. A total outpu…
Single-beam noise characteristics of quantum correlated twin beams
Yun Zhangx, Katsuyuki Kasai, Kazuhiro Hayasaka
We investigated the intensity noise spectra of the single beam of a pump-enhanced continuous-wave (cw) optical parametric oscillator (OPO), which was used to generate quantum corre…
Quantum channel using photon number correlated twin beams
Yun Zhang, Katsuyuki Kasai, Kazuhiro Hayasaka
We report quantum communications channel using photon number correlated twin beams. The twin beams are generated from a nondegenerate optical parametric oscillator, and the photon…
