Topological defect formation in 1D and 2D spin chains realized by network of optical parametric oscillators
Ryan Hamerly, Kensuke Inaba, Takahiro Inagaki +3
A network of optical parametric oscillators is used to simulate classical Ising and XY spin chains. The collective nonlinear dynamics of this network, driven by quantum noise rathe…
Large-scale Ising spin network based on degenerate optical parametric oscillators
Takahiro Inagaki, Kensuke Inaba, Ryan Hamerly +3
Simulating a network of Ising spins with physical systems is now emerging as a promising approach for solving mathematically intractable problems. Here we report a large-scale netw…
Enhanced violation of the Collins-Gisin-Linden-Massar-Popescu inequality with optimized time-bin-entangled ququarts
Takuya Ikuta, Hiroki Takesue
High-dimensional quantum entanglement is drawing attention because it enables us to perform quantum information tasks that are robust against noises. To test the nonlocality of ent…
