SnapshotStatevector¶

class SnapshotStatevector(label, num_qubits=0)[ソース]¶

ベースクラス: qiskit.providers.aer.extensions.snapshot.Snapshot

Snapshot instruction for statevector snapshot type

Create a statevector state snapshot instruction.

パラメータ

label (str) – the snapshot label.
num_qubits (int) – the instruction barrier size [Default: 0].

例外

ExtensionError – if snapshot is invalid.

Additional Information:: This snapshot is always performed on all qubits in a circuit. The number of qubits parameter specifies the size of the instruction as a barrier and should be set to the number of qubits in the circuit.

バージョン 0.9.0 で非推奨: This instruction has been deprecated and will be removed no earlier than 3 months from the 0.9.0 release date. It has been superseded by the qiskit.providers.aer.library.SaveStatevector instruction.

Methods

`add_decomposition`	Add a decomposition of the instruction to the SessionEquivalenceLibrary.
`assemble`	Assemble a QasmQobjInstruction
`broadcast_arguments`	Validation of the arguments.
`c_if`	Set a classical equality condition on this instruction between the register or cbit `classical` and value `val`.
`copy`	Copy of the instruction.
`define_snapshot_register`	Defines qubits to snapshot for all snapshot methods
`inverse`	Special case.
`is_parameterized`	Return True .IFF.
`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.
