Quantum Fourier transform spectroscopy of biexciton
Hiroya Seki, Kensuke Miyajima, Ryosuke Shimizu
Fourier transform spectroscopy with classical interferometry corresponds to the measurement of a single-photon intensity spectrum from the viewpoint of the particle nature of light…
Quantum sum-frequency interference using up-converted photon pairs
A. Syouji, R. Shimizu, S. Nagano +2
We demonstrate a hybrid approach to the generation of photon pairs of a short wavelength with high brightness, by combining parametric down-conversion (SPDC) and up-conversion tech…
Broadband-laser-diode pumped PPKTP-Sagnac polarization-entangled photon source
Neng Cai, Wu-Hao Cai, Shun Wang +3
We experimentally demonstrate a polarization-entangled photon source at 810 nm using a type-II phase-matched PPKTP crystal pumped by a low-cost, broadband laser diode with a centra…
Spectrally resolved NOON state interference
Rui-Bo Jin, Ryosuke Shimizu, Takafumi Ono +5
NOON state interference (NOON-SI) is a powerful tool to improve the phase sensing precision, and plays an important role in quantum measurement. In most of the previous NOON-SI exp…
