2025-T1: Performance improvements for large circuits

No due date 11% complete

Cirq gets slow for circuits of ~100 qubits. Users have raised concerns about memory needs and ability to handle circuits of 500 or 1000 qubits.

We still need to clarify:

  • What use cases are already slow at 100 qubit size?
  • When do we need the capability to handle circuits of 500 and 1000 qubits?
  • What functions and use cases need to be covered for circuits …
