SnapshotStatevector¶
-
class
SnapshotStatevector
(label, num_qubits=0)[source]¶ Bases:
qiskit.providers.aer.extensions.snapshot.Snapshot
Snapshot instruction for statevector snapshot type
Create a statevector state snapshot instruction.
- Parameters
label (str) – the snapshot label.
num_qubits (int) – the instruction barrier size [Default: 0].
- Raises
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.
Note
This instruction will be deprecated after the qiskit-aer 0.8 release. It has been superseded by the
qiskit.providers.aer.library.SaveStatevector
instruction.Methods
Add a decomposition of the instruction to the SessionEquivalenceLibrary.
Assemble a QasmQobjInstruction
Validation of the arguments.
Add classical condition on register or cbit classical and value val.
Copy of the instruction.
Defines qubits to snapshot for all snapshot methods
Special case.
Return True .IFF.
DEPRECATED: use instruction.reverse_ops().
Return a default OpenQASM string for the instruction.
Creates an instruction with gate repeated n amount of times.
For a composite instruction, reverse the order of sub-instructions.
Soft comparison between gates.
Instruction parameters has no validation or normalization.
