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…
Quantum-inspired Ising machine using sparsified spin connectivity
Moe Shimada, Koki Awaya, Ryoya Yonemoto +2
Combinatorial optimization problems become computationally intractable as these NP-hard problems scale. We previously proposed extraction-type majority voting logic (E-MVL), a quan…
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…
