Quantum computation of a quasiparticle band structure with the quantum-selected configuration interaction
Takahiro Ohgoe, Hokuto Iwakiri, Kazuhide Ichikawa +2
Quasiparticle band structures are fundamental for understanding strongly correlated electron systems. While solving these structures accurately on classical computers is challengin…
Demonstrating Quantum Computation for Quasiparticle Band Structures
Takahiro Ohgoe, Hokuto Iwakiri, Masaya Kohda +4
Understanding and predicting the properties of solid-state materials from first-principles has been a great challenge for decades. Owing to the recent advances in quantum technolog…
Deep variational quantum eigensolver for excited states and its application to quantum chemistry calculation of periodic materials
Kaoru Mizuta, Mikiya Fujii, Shigeki Fujii +4
A programmable quantum device that has a large number of qubits without fault-tolerance has emerged recently. Variational Quantum Eigensolver (VQE) is one of the most promising way…
Quantum stream cipher by Yuen 2000 protocol: Design and experiment by intensity modulation scheme
Osamu Hirota, Masaki Sohma, Masaru Fuse +1
This paper shall investigate Yuen protocol, so called Y-00, which can realize a randomized stream cipher with high bit rate(Gbps) for long distance(several hundreds km). The random…
A quantum symmetric key cipher(Y-00) and key generation (Quantum stream cipher-Part II)
Osamu Hirota, Kentaro Kato, Masaki Sohma +1
What obstructs the realization of useful quantum cryptography is single photon scheme, or entanglement which is not applicable to the current infrastructure of optical communicatio…
Quantum key distribution with unconditional security for all optical fiber network
Osamu Hirota, Kentaro Kato, Masaki Shoma +1
In this paper, we present an efficient implementation method of physical layer of Y-00 which can support a secure communication and a quantum key distribution (more generally key e…
