| | [qsim](https://github.com/quantumlib/qsim) | qsimcirq | Implements `SimulatesAmplitudes` and `SimulatesFinalState`. Recommended for deep circuits with up to 30 qubits (consumes 8GB RAM). Larger circuits are possible, but RAM usage doubles with each additional qubit. | | ||
| | [qsimh](https://github.com/quantumlib/qsim/blob/master/qsimcirq/qsimh_simulator.py) | qsimcirq | Implements `SimulatesAmplitudes`. Intended for heavy parallelization across several computers; Cirq users should generally prefer one of the other simulators listed here. | | ||
| | [qFlex](https://github.com/ngnrsaa/qflex) | qflexcirq | Implements `SimulatesAmplitudes`. Recommended for shallow / low-entanglement circuits with more than 30 qubits. RAM usage is highly dependent on the number of two-qubit gates in the circuit. | |

I've checked in with the team - they're currently working to get it online. Once that link resolves I'll go ahead with the merge.

That link is now happy - pip3 install qflexcirq should work as expected.

Added notes on
qsim[h]andqFlex, with links to their respective repositories.Notably, neither of these currently support
SimulatesSamples, although it wouldn't be too costly to distill samples from the results of aqsimfull-state simulation.
