Vanadium superconducting microwave resonators on silicon wafers
Y. Fujita, Y. Urade, Y. Hibino +4
Understanding the correlation between material properties and microwave losses in superconducting films is a crucial subject for developing low-loss materials for quantum circuits.…
Toward Practical-Scale Quantum Annealing Machine for Prime Factoring
Masaaki Maezawa, Go Fujii, Mutsuo Hidaka +8
We propose a prime factorizer operated in a framework of quantum annealing (QA). The idea is inverse operation of a multiplier implemented with QA-based Boolean logic circuits. We…
Development FD-SOI MOSFET amplifiers for integrated read-out circuit of superconducting-tunnel-junction single-photon-detectors
Kenji Kiuchi, Shinhong Kim, Yuji Takeuchi +28
We proposed a new high resolution single photon infrared spectrometer for search for radiative decay of cosmic neutrino background(CB). The superconducting-tunnel-junctions(STJs…
Quantum receiver beyond the standard quantum limit of coherent optical communication
Kenji Tsujino, Daiji Fukuda, Go Fujii +4
The most efficient modern optical communication is known as coherent communication and its standard quantum limit (SQL) is almost reachable with current technology. Though it has b…
Sub-shot-noise-limit discrimination of on-off keyed coherent signals via a quantum receiver with a superconducting transition edge sensor
Kenji Tsujino, Daiji Fukuda, Go Fujii +4
We demonstrate a sub-shot-noise-limit discrimination of on-off keyed coherent signals by an optimal displacement quantum receiver in which a superconducting transition edge sensor…
