SaveDensityMatrix¶
- class SaveDensityMatrix(num_qubits, label='density_matrix', unnormalized=False, pershot=False, conditional=False)[소스]¶
기반 클래스:
SaveAverageData
Save a reduced density matrix.
Create new instruction to save the simulator reduced density matrix.
- 매개변수
num_qubits (int) – the number of qubits for the save instruction.
label (str) – the key for retrieving saved data from results.
unnormalized (bool) – If True return save the unnormalized accumulated or conditional accumulated density matrix over all shots [Default: False].
pershot (bool) – if True save a list of density matrices for each shot of the simulation rather than the average over all shots [Default: False].
conditional (bool) – if True save the average or pershot data conditional on the current classical register values [Default: False].
Methods
Add a decomposition of the instruction to the SessionEquivalenceLibrary.
Return the QasmQobjInstruction for the intructions.
Validation of the arguments.
Set a classical equality condition on this instruction between the register or cbit
classical
and valueval
.Copy of the instruction.
Special case.
Return True .IFF.
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.
