Publikováno v: Physical review letters. 125(26)

Optical approaches to quantum computation require the creation of multi-mode photonic quantum states in a controlled fashion. Here we experimentally demonstrate phase locking of two all-optical quantum memories, based on a concatenated cavity system

Generation of two-mode quantum states of light with timing controllable memories

Autor: Mamoru Endo, Akira Furusawa, Yuya Ishizuka, Mikihisa Matsuyama, Rei Sakakibara, Jun-ichi Yoshikawa, Fumiya Okamoto, Yosuke Hashimoto, Peter van Loock

Publikováno v: Conference on Lasers and Electro-Optics.

We created and experimentally verified two-mode entangled states of light, α|0,1⟩ + βe*+|1,0⟩, by means of two phase-sensitive optical quantum memories. The release timing of each optical mode can be independently controlled for up to 400 ns.

All-Optical Storage of Phase-Sensitive Quantum States of Light

Autor: Takeshi Toyama, Peter van Loock, Akira Furusawa, Yosuke Hashimoto, Rei Sakakibara, Shuntaro Takeda, Kenzo Makino, Fumiya Okamoto, Jun-ichi Yoshikawa

Publikováno v: Physical review letters. 123(11)

We experimentally demonstrate storage and on-demand release of phase-sensitive, photon-number superposition states of the form $\alpha |0\rangle + \beta e^{i\theta} |1\rangle$ for an optical quantized oscillator mode. For this purpose, we introduce a
