# SetDensityMatrix¶

class SetDensityMatrix(state)[ソース]

ベースクラス: qiskit.circuit.instruction.Instruction

Set density matrix state of the simulator

Create new instruction to set the density matrix state of the simulator.

パラメータ

state (DensityMatrix) – a density matrix.

ExtensionError – if the input density matrix is not valid.

This set instruction must always be performed on the full width of qubits in a circuit, otherwise an exception will be raised during simulation.

Methods

 add_decomposition Add a decomposition of the instruction to the SessionEquivalenceLibrary. assemble Assemble a QasmQobjInstruction broadcast_arguments Validation of the arguments. c_if Add classical condition on register or cbit classical and value val. copy Copy of the instruction. inverse Invert this instruction. is_parameterized Return True .IFF. mirror DEPRECATED: use instruction.reverse_ops(). qasm Return a default OpenQASM string for the instruction. repeat Creates an instruction with gate repeated n amount of times. reverse_ops For a composite instruction, reverse the order of sub-instructions. soft_compare Soft comparison between gates. validate_parameter Instruction parameters has no validation or normalization.
