Subsampling Factorization Machine Annealing
Yusuke Hama, Tadashi Kadowaki
Quantum computing and machine learning are state-of-the-art technologies that have been investigated intensively in both academia and industry. The hybrid technology of these two i…
Quantum-Error-Mitigation Circuit Groups for Noisy Quantum Metrology
Yusuke Hama, Hirofumi Nishi
Quantum technologies work by utilizing properties inherent in quantum systems such as quantum coherence and quantum entanglement and are expected to be superior to classical counte…
Quantum Error Mitigation via Quantum-Noise-Effect Circuit Groups
Yusuke Hama, Hirofumi Nishi
Near-term quantum computers have been built as intermediate-scale quantum devices and are fragile against quantum noise effects, namely, NISQ devices. Traditional quantum-error-cor…
Quantum Circuits for Collective Amplitude Damping in Two-Qubit Systems
Yusuke Hama
Quantum computers have now appeared in our society and are utilized for the investigation of science and engineering. At present, they have been built as intermediate-size computer…
Relaxation to Negative Temperatures in Double Domain Systems
Yusuke Hama, William J. Munro, Kae Nemoto
We investigate the relaxation of two collective spins in double domain system, which are individually coupled to a single bosonic reservoir, by varying the total number of spins in…
