Completely scrambled memory for quantum superposition
Tetsuya Mukai
Although constructing a quantum computation device with multiple qubits is arguably a difficult task, several seconds of coherence time with tens of thousands of quantum particles…
Polarization insensitive frequency conversion for an atom-photon entanglement distribution via a telecom network
Rikizo Ikuta, Toshiki Kobayashi, Tetsuo Kawakami +8
Quantum network with a current telecom photonic infrastructure is deficient in quantum storages that keep arbitrary quantum state in sufficient time duration for a long-distance qu…
Security enhanced memory for quantum state
Tetsuya Mukai
Security enhancement is important in terms of both classical and quantum information. The recent development of a quantum storage device is noteworthy, and a coherence time of one…
Ultrafast coherent control of spinor Bose-Einstein condensates using stimulated Raman adiabatic passage
Andreas Thomasen, Tetsuya Mukai, Tim Byrnes
We propose the use of stimulated Raman adiabatic passage (STIRAP) to offer a fast high fidelity method of performing SU(2) rotations on spinor Bose Einstein condensates (BEC). Past…
Heralded single excitation of atomic ensemble via solid-state-based telecom photon detection
Rikizo Ikuta, Toshiki Kobayashi, Kenichiro Matsuki +7
Telecom photonic quantum networks with matter quantum systems enable a rich variety of applications, such as a long distance quantum cryptography and one-way quantum computing. Pre…
Macroscopic quantum information processing using spin coherent states
Tim Byrnes, Daniel Rosseau, Megha Khosla +6
Previously a new scheme of quantum information processing based on spin coherent states of two component Bose-Einstein condensates was proposed (Byrnes {\it et al.} Phys. Rev. A 85…
