Multi-impurity method for the bond-weighted tensor renormalization group

Satoshi Morita, Naoki Kawashima

We propose a multi-impurity method for the bond-weighted tensor renormalization group (BWTRG) to compute the higher-order moment of physical quantities in a two-dimensional system.…

Advantages of fixing spins in quantum annealing

Tomohiro Hattori, Hirotaka Irie, Tadashi Kadowaki +1

Quantum annealing can efficiently obtain solutions to combinatorial optimization problems. Size-reduction methods are used to treat large-scale combinatorial optimization problems…

Entanglement Spectrum Dynamics as a Probe for Non-Hermitian Bulk-Boundary Correspondence in Systems with Periodic Boundaries

Pablo Bayona-Pena, Ryo Hanai, Takashi Mori +1

It has recently been established that open quantum systems may exhibit a strong spectral sensitivity to boundary conditions, known as the non-Hermitian/Liouvillian skin effect (NHS…

Quick design of feasible tensor networks for constrained combinatorial optimization

Hyakka Nakada, Kotaro Tanahashi, Shu Tanaka

Quantum computers are expected to enable fast solving of large-scale combinatorial optimization problems. However, their limitations in fidelity and the number of qubits prevent th…

Annealing-Assisted Column Generation for Inequality-Constrained Combinatorial Optimization Problems

Hiroshi Kanai, Masashi Yamashita, Kotaro Tanahashi +1

Ising machines are expected to solve combinatorial optimization problems faster than the existing integer programming solvers. These problems, particularly those encountered in pra…

Strong Markov dissipation in driven-dissipative quantum systems

Takashi Mori

The Lindblad equation, which describes Markovian quantum dynamics under dissipation, is usually derived under the weak system-bath coupling assumption. Strong system-bath coupling…
