Superconducting Acousto-optic Phase Modulator
Ayato Okada, Rekishu Yamazaki, Maria Fuwa +9
We report the development of a superconducting acousto-optic phase modulator fabricated on a lithium niobate substrate. A titanium-diffused optical waveguide is placed in a surface…
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…
Spectral characterization of photon-pair sources via classical sum-frequency generation
Fumihiro Kaneda, Jo Oikawa, Masahiro Yabuno +5
Tailoring spectral properties of photon pairs is of great importance for optical quantum information and measurement applications. High-resolution spectral measurement is a key tec…
Experimental demonstration of a quantum receiver beating the standard quantum limit at the telecom wavelength
Shuro Izumi, Jonas S. Neergaard-Nielsen, Shigehito Miki +2
Discrimination of coherent states beyond the standard quantum limit (SQL) is an important tasknot only for quantum information processing but also for optical coherent communicatio…
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 (…
