调研方向

Start with the existing QasmModule class and its .unroll(device_qubits) method, since the merge depends on how they consolidate registers into __PYQASM_QUBITS__ and __PYQASM_CLASSICAL__. Decide how the default device_qubits should be chosen and how gates and operation history from both modules combine. Done means a new merged module comes back with consolidated registers, with the original modules left unchanged, and tests cover merging two modules that use different register layouts.

Feature Description

Implement a.merge() method with automatic unrolling and register consolidation.

  • Purpose:
    Merge two QasmModule objects into a single module, handling all register consolidation and unrolling transparently.
  • Consolidation & Unrolling:
    • All register consolidation and unrolling is performed automatically during the merge.
    • Uses the existing .unroll(device_qubits) method to ensure both modules are unrolled and consolidated before merging.
  • User Experience:
    • The user only needs to call .merge() on one module, passing the other as an argument.
    • No manual unrolling or consolidation is required.
  • Output:
    • Returns a new, merged module (preferred for immutability).
    • All qubit and classical registers are consolidated into __PYQASM_QUBITS__ and __PYQASM_CLASSICAL__.
Implementation (Optional)
  1. Unroll and Consolidate Both Modules:
    • Call .unroll(device_qubits=...) on both modules before merging.
    • If device_qubits is not specified, use a default large enough to hold all qubits.
    • This ensures all registers are consolidated and unrolled.
  2. Merge Gates and Operation History:
    • Append gates from the second module after the first.
    • Combine operation history lists.
  3. Consolidate the Merged Module (Optional, but Safe):
    • If the merge could introduce new registers (unlikely if both are already consolidated), perform a final consolidation.
    • This step is mostly redundant but ensures robustness.
  4. Return the New Module:
    • Return a new QasmModule with the merged content.
