`AbstractCircuit.freeze` should not reallocate moments

2

**Description of the issue** When freezing circuits, `Moment` instances should be reused since they are immutable. This was previously the case, but seems to have changed recently (possibly due to...

This would be convenient for testing and comparing simulators on different instruction sets from python.

This is something we use on our internal version of this gate.

This is a proposal to make `transformer_primitives` functions available as methods on `TransformerContext`. Then they can be invoked without passing extra parameters which are already stored on the context, such...

This is a first step toward supporting repeated keys in circuits run through quantum engine. I need to expand the tests to cover cases where instances > 1, but the...

Ignore spurious PollerCompletionQueue errors in AsyncioExecutor

1

When using grpc with asyncio from multiple threads, spurious `PollerCompletionQueue` errors are printed due to multiple event loops listening a socket to be notified of grpc events. More than one...

[Python] Handle BlockingIOError if multiple loops are bound to PollerCompletionQueue

2

Fixes #25364 When using grpc with multiple asyncio event loops in different threads, we may have multiple loops bound to the same `PollerCompletionQueue`. If the event loops support file descriptor...

Compute block_counts iteratively with explicit stack

1

I get recursion errors when converting some large profiles with flameprof. This change avoids these RecursionErrors by using iteration with an explicit stack to compute block counts. Could get a...

Need padding for compatibility with RFC 5054

1

The implementation here seems to be incompatible with the specification of SRP in RFC 5054 which requires padding in various places that is not applied here. For example, in [section...
