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…
Nonlocal Variable-Strength Measurements of N Qubits Using GHZ-like Entanglement
Pierre Vidil, Keiichi Edamatsu
The direct measurement of nonlocal properties of entangled quantum systems has been the subject of several recent experimental investigations. Of particular interest is the impleme…
