Potts model solver based on hybrid physical and digital architecture
2022 · Communications Physics
Abstract The Potts model describes Ising-model-like interacting spin systems with multivalued spin components, and ground-state search problems of the Potts model can be efficiently mapped onto various integer optimization problems thanks to the rich expression …

Optical Waveform Engineering of Non-Gaussian States
2023
Toward the realization of quantum information processing (QIP), continuous-variable (CV) system is a promising candidate, where scalable quantum information processors are already demonstrated [1]. The next milestone is the demonstration of universality and fault-tolerance on …

Next Generation Optical Quantum State Synthesis: Observation of Fourfold Negativity in the Wigner Function
2024
An optical quantum state with fourfold Wigner negativity was generated without any loss correction. Generalized photon subtraction scheme, broadband squeezed light source, and high-temporal-resolution transition-edge sensor enabled generation rates of tens of counts per second.
