Free-space optical channel estimation for physical layer security
Hiroyuki Endo, Mikio Fujiwara, Mitsuo Kitamura +10
We present experimental data on message transmission in a free-space optical (FSO) link at an eye-safe wavelength, using a testbed consisting of one sender and two receiver termina…
Detection-dependent six-photon NOON state interference
Rui-Bo Jin, Mikio Fujiwara, Ryosuke Shimizu +7
NOON state interference (NOON-SI) is a powerful tool to improve the phase sensing precision, and can play an important role in quantum sensing and quantum imaging. However, most of…
Generation and distribution of high-dimensional frequency-entangled qudits
Rui-Bo Jin, Ryosuke Shimizu, Mikio Fujiwara +7
We demonstrate a novel scheme to generate frequency-entangled qudits with dimension number higher than 10 and to distribute them over optical fibers of 15 km in total length. This…
