"automatic", "statevector", "density_matrix" Set the simulator state to the specified statevector The AerSimulator allows setting a custom simulator state for several of its simulation methods using custom simulator instructions Setting the simulator to a custom state ΒΆ Note that these instructions are only supported by the Aer simulator and will result in an error if a circuit containing them is run on a non-simulator backend such as an IBM Quantum device. Save the simulator state as superoperator matrix of the run circuit
Save the simulator state as unitary matrix of the run circuit Save the simulator state as a a matrix product state tensor "automatic", "statevector", "matrix_product_state", "density_matrix" Save the simulator state as a density matrix Save the simulator state as a Clifford stabilizer "automatic", "statevector", "matrix_product_state", "extended_stabilizer" Save the simulator state as a statevector Save the simulator state in the native format for the simulation method The state of the simulator can be saved in a variety of formats using custom simulator instructions. get_counts ( 0 ) plot_histogram (, title = 'Counts for different simulation methods', legend = ) run ( circ, shots = shots ) counts_mps = job_mps. get_backend ( 'aer_simulator_matrix_product_state' ) job_mps = sim_mps. get_counts ( 0 ) # Matrix Product State simulation method sim_mps = Aer. run ( circ, shots = shots ) counts_density = job_density.
