Quantum Nondemolition Gate Operations and Measurements in Real Time on Fluctuating Signals
Yu Shiozawa, Jun-ichi Yoshikawa, Shota Yokoyama +10
We demonstrate an optical quantum nondemolition (QND) interaction gate with a bandwidth of about 100 MHz. Employing this gate, we are able to perform QND measurements in real time…
Heralded creation of photonic qudits from parametric down conversion using linear optics
Jun-ichi Yoshikawa, Marcel Bergmann, Peter van Loock +7
We propose an experimental scheme to generate, in a heralded fashion, arbitrary quantum superpositions of two-mode optical states with a fixed total photon number based on weak…
Direct observation of phase sensitive Hong-Ou-Mandel interference
Petr Marek, Petr Zapletal, Radim Filip +5
Quality of individual photons and their ability to interfere is traditionally tested by measuring the Hong-Ou-Mandel photon bunching effect. However, this phase insensitive measure…
