Two-photon interference at telecom wavelengths for time-bin-encoded single photons from quantum-dot spin qubits
2015 · Nature Communications
Practical quantum communication between remote quantum memories rely on single photons at telecom wavelengths. Although spin-photon entanglement has been demonstrated in atomic and solid-state qubit systems, the produced single photons at short wavelengths and with …

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 …

Control of amplitude homogeneity in coherent Ising machines with artificial Zeeman terms
2022 · Communications Physics
Abstract A coherent Ising machine (CIM) is an open-dissipative Ising solver using optical pulses generated from a degenerate optical parametric oscillator as analog magnetizations. When solving real-world optimization problems with CIM, this solver has two …
