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…

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…
