The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Topological dissipation in a time-multiplexed photonic resonator network (2021, positive): “Such ‘dissipation engineer-ing’ plays an important role in superconducting circuits, ultracold atoms and photonics, where it is used for reservoir engineering 9 , laser mode-locking 10,11 , and quantum and photonic computing 12–14 .”
100,000-spin coherent Ising machine (2021, positive): “In our previous report ( 18 ), we used Goemans-Williamson semidefinite programming (GW-SDP) ( 36 ), which is a relaxation algorithm that theoretically guarantees the solution accuracy.”
Quantum Approximate Optimization Algorithm: Performance, Mechanism, and Implementation on Near-Term Devices (2018, background): “[64] Takahiro Inagaki, Yoshitaka Haribara, Koji Igarashi, Tomohiro Sonobe, Shuhei Tamate, Toshimori Honjo, Alireza Marandi, Peter L.”
Combinatorial optimization by simulating adiabatic bifurcations in nonlinear Hamiltonian systems (2019, methodology): “From these results, we conclude that our single-FPGA SB machine is about 10 times faster than the CIM developed in ( 17 ).”
Tunable-range, photon-mediated atomic interactions in multimode cavity QED (2017, background): “In this way, Hopfield associative memories [13, 52, 55, 56] and coherent Ising machines [57, 58] may be implemented in the presence of quantum effects like spin entanglement and quantum criticality, providing a new route to quantum neuromorphic computation.”
