Enhanced coherence of all-nitride superconducting qubits epitaxially grown on silicon substrate
Sunmi Kim, Hirotaka Terai, Taro Yamashita +6
Improving the coherence of superconducting qubits is a fundamental step towards the realization of fault-tolerant quantum computation. However, coherence times of quantum circuits…
Boosting the secret key rate in a shared quantum and classical fibre communication system
Davide Bacco, Beatrice Da Lio, Daniele Cozzolino +14
During the last 20 years, the advance of communication technologies has generated multiple exciting applications. However, classical cryptography, commonly adopted to secure curren…
Robust entanglement distribution via telecom fibre assisted by an asynchronous counter-propagating laser light
Koichiro Miyanishi, Yoshiaki Tsujimoto, Rikizo Ikuta +7
Distributing entangled photon pairs over noisy channels is an important task for various quantum information protocols. Encoding an entangled state in a decoherence-free subspace (…
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…
Silicon photonic processor of two-qubit entangling quantum logic
R. Santagati, J. W. Silverstone, M. J. Strain +11
Entanglement is a fundamental property of quantum mechanics, and is a primary resource in quantum information systems. Its manipulation remains a central challenge in the developme…
Mach-Zehnder interferometer using frequency-domain beamsplitter
Toshiki Kobayashi, Daisuke Yamazaki, Kenichiro Matsuki +7
We demonstrated the first-order interference between coherent light at 1580 nm and 795 nm by using frequency-domain Mach-Zehnder interferometer (MZI). The MZI is implemented by two…
