Please go ahead and make the PR @InfamousPlatypus . Thanks!

This bug reproduces on my end as well. I'm using qiskit_aer `0.13.3`, i.e. an older version than above, but still seeing the same issue. I played with one of the...

Here is a much simpler circuit that reproduces the problem: ``` qc = QuantumCircuit(3,1) qc.h([0,1]) qc.cx(1,2) qc.cy(0,1) qc.cy(0,2) qc.h(0) qc.measure(0,0) ```

Thank you @doichanj for your quick work on this! Do you know what conditions would cause the stabilizer simulator to give the wrong answer? This info could help decide whether...

A small baby-step towards U != V could be taking the counts object returned from the backend (if that is available for now), and randomly assigning half the shots to...

LGTM. Belated thanks to @InfamousPlatypus ! 

Just to emphasize the severity: for an `Operator` on tens of qubits, "large" here can mean petabytes, so the program immediately crashes.

Since this issue has been idle for a while, just wanted to say I recently hit the same bottleneck described in this issue, and found the linked `qrusty` code still...

Thanks Jake, that's very cool you can match the performance even single-threaded. It's not pressing but I'd be interested in trying your method at some point. The convenience/portability of being...
