Demonstration of a Coherent Tunable Amplifier for All-Optical Ising Machines

2017

Coherent Ising machines are a type of optical accelerators that can solve different optimization tasks by encoding the problem in the connection matrix of the network. So far, experimental realizations have been limited to time …

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 …
