Complementary quantum and classical records of qubit decoherence
Jargalsaikhan Artag, Koki Awaya, Takumi Kanezashi +4
Decoherence is usually viewed as the loss of local coherence, but it also writes information into the environment. Here we show that the environment stores this information in two…
All-valid-state HOBO encoding for constrained combinatorial optimization on NISQ devices
Juncheng Wang, Takumi Kanezashi, Daisuke Tsukayama +5
Continued advancements in quantum computing have stimulated growing interest in translating quantum technologies into real-world applications. Consequently, the investigation of pr…
Utility of NISQ devices: optimizing experimental parameters for the fabrication of Au atomic junction using gate-based quantum computers
Takumi Kanezashi, Daisuke Tsukayama, Jun-ichi Shirakashi +2
Feedback-controlled electromigration (FCE) enables precise regulation of atomic migration by carefully optimizing multiple experimental parameters. However, manually fine-tuning th…
Multi-tasking through quantum annealing
Jargalsaikhan Artag, Koki Awaya, Takumi Kanezashi +3
Quantum annealing approximately solves combinatorial optimization problems by leveraging the principles of adiabatic quantum systems. In this approach, the system's Hamiltonian evo…
