QPU simulator backend

[vrpascuzzi]

I have yet to see "XPU" with 'X' == 'Q'. Something I'm interested in is having qpu_selector, where this would use a QC simulator (akin to, e.g., an FPGA simulator) for Qiskit, cirq, DM-Sim, etc., perhaps via a PI interface?

I realize interoperability is an option to call functions from a 3rd party library, but wouldn't it be cool to have an actual interace/selector for a QPU? Useful for QAOA, VQE, QML, ....

What other programming models have this capability? None. However, do see: QCOR, BSQKit, ....

Also interested? Let's discuss.
