Informations
- Qiskit Aer version: 0.11.1
- Python version: 3.8
- Operating system: MacOS
What is the current behavior?
AerState uses mc* instructions, which are not supported in matrix_product_state method
Steps to reproduce the problem
from qiskit_aer.quantum_info.states import AerStatevector
from qiskit_aer.quantum_info.states.aer_state import AerState
from qiskit.circuit.library import QFT
AerStatevector(QFT(4), method='statevector') #ok
AerStatevector(QFT(4), method='matrix_product_state') #ng
What is the expected behavior?
Pass the above code.
Suggested solutions
AerState supports apply_u and apply_cx and _aer_evolve_circuit checks basic gates of a method.
