Wave-particle duality of unpolarized photons
Naofumi Abe, Keiichi Edamatsu
Photons in a two-path interferometer best embody wave-particle duality (WPD), which is a core concept of quantum theory. So far, the WPD relation is commonly written as $V^2+D^2 \l…
Plasmon-enhanced polarized single photon source directly coupled to an optical fiber
Masakazu Sugawara, Yining Xuan, Yasuyoshi Mitsumori +2
A bright source of fiber-coupled, polarized single photons is an essential component of any realistic quantum network based on today's existing fiber infrastructure. Here, we devel…
Error-disturbance uncertainty relations in Faraday measurements
Le Bin Ho, Keiichi Edamatsu
We examine error-disturbance relations in the quantum measurement of spin systems using an atom-light interface scheme. We model a single spin-1/2 system that interacts with a pola…
Generation of spectrally factorable photon pairs via multi-order quasi-phase-matched spontaneous parametric downconversion
Fumihiro Kaneda, Jo Oikawa, Masahiro Yabuno +5
For advanced quantum information technology, sources of photon pairs in quantum mechanically factorable states are of great importance for realizing high-fidelity photon-photon qua…
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…
Optically induced sieve effect for nanoparticles near a nanofiber taper
Mark Sadgrove, Takaaki Yoshino, Masakazu Sugawara +2
We demonstrate size selective optical trapping and transport for nanoparticles near an optical nanofiber taper. Using a two-wavelength, counter-propagating mode configuration, we s…
