Photonic coherent reservoir computer based on fiber-ring with distributed nonlinearity
2020
We exploit the transient dynamics of a nonlinear photonic system to perform useful computation. This is achieved within the framework of reservoir computing. State of the art implementations in photonic hardware are evolving towards simple …

Broadening the set of algorithms and use-cases for analog combinatorial optimization accelerators
2021
Recent experimental results show how classical accelerators based on analog computing can outperform quantum annealing alternatives in benchmark tasks that require dense connection matrices. In Hewlett Packard Labs, we have been studying two alternatives: integrated …

High-Speed Reservoir Computing with Spin-VCSELs
2021
We introduce a reservoir computing scheme where a VCSEL with optical spin injection and delayed optical feedback serves as a reservoir. Polarization modulation is considerably faster than intensity modulation, allowing a tenfold increase of processing …

Requirements on bit resolution in optical Ising machine implementations with analog spin variables
2025 · Communications Physics
Abstract Optical Ising machines have emerged as a promising dynamical hardware solver for computational hard optimization problems. These Ising machines typically require an optical modulator to represent the analog spin variables of these problems. However, …
