What is the expected feature or enhancement?

Currently we hard code the QPY version used to 11:

qiskit-ibm-runtime/qiskit_ibm_runtime/utils/json.py

Lines 260 to 263 in 0f345d8

if isinstance(obj, QuantumCircuit):
kwargs: Dict[str, object] = {"use_symengine": bool(optionals.HAS_SYMENGINE)}
if _TERRA_VERSION[0] >= 1:
kwargs["version"] = 11

QPY 13 (from Qiskit 1.3) made some improvement by removing symengine, so we should be using that version. This implies requiring Qiskit 1.3, which should be fine given there shouldn't be any breaking changes within the same major version. This would have to wait for Qiskit Runtime service to support 1.3 first though, and deprecation warning issued by 1.3 should be fixed.

Acceptance criteria

  • Use QPY 13 once the server side supports it.
