SetMatrixProductState
SetMatrixProductState(state)
Bases: qiskit.circuit.instruction.Instruction
Set the matrix product state of the simulator
Create new instruction to set the matrix product state of the simulator.
Parameters
state (Tuple[List[Tuple[np.array[complex_t]]]], List[List[float]]) – A matrix_product_state.
This set instruction must always be performed on the full width of qubits in a circuit. The matrix_product_state consists of a pair of vectors. The first is a vector of pairs of matrices of complex numbers. The second is a vector of vectors of double.
Methods
add_decomposition
SetMatrixProductState.add_decomposition(decomposition)
Add a decomposition of the instruction to the SessionEquivalenceLibrary.
assemble
SetMatrixProductState.assemble()
Assemble a QasmQobjInstruction
broadcast_arguments
SetMatrixProductState.broadcast_arguments(qargs, cargs)
Validation of the arguments.
Parameters
- qargs (List) – List of quantum bit arguments.
- cargs (List) – List of classical bit arguments.
Yields
Tuple(List, List) – A tuple with single arguments.
Raises
CircuitError – If the input is not valid. For example, the number of arguments does not match the gate expectation.
c_if
SetMatrixProductState.c_if(classical, val)
Set a classical equality condition on this instruction between the register or cbit classical and value val.
This is a setter method, not an additive one. Calling this multiple times will silently override any previously set condition; it does not stack.
copy
SetMatrixProductState.copy(name=None)
Copy of the instruction.
Parameters
name (str) – name to be given to the copied circuit, if None then the name stays the same.
Returns
a copy of the current instruction, with the name
updated if it was provided
Return type
inverse
SetMatrixProductState.inverse()
Invert this instruction.
If the instruction is composite (i.e. has a definition), then its definition will be recursively inverted.
Special instructions inheriting from Instruction can implement their own inverse (e.g. T and Tdg, Barrier, etc.)
Returns
a fresh instruction for the inverse
Return type
Raises
CircuitError – if the instruction is not composite and an inverse has not been implemented for it.
is_parameterized
SetMatrixProductState.is_parameterized()
Return True .IFF. instruction is parameterized else False
mirror
SetMatrixProductState.mirror()
DEPRECATED: use instruction.reverse_ops().
Returns
a new instruction with sub-instructions
reversed.
Return type
qasm
SetMatrixProductState.qasm()
Return a default OpenQASM string for the instruction.
Derived instructions may override this to print in a different format (e.g. measure q[0] -> c[0];).
repeat
SetMatrixProductState.repeat(n)
Creates an instruction with gate repeated n amount of times.
Parameters
n (int) – Number of times to repeat the instruction
Returns
Containing the definition.
Return type
Raises
CircuitError – If n < 1.
reverse_ops
SetMatrixProductState.reverse_ops()
For a composite instruction, reverse the order of sub-instructions.
This is done by recursively reversing all sub-instructions. It does not invert any gate.
Returns
a new instruction with
sub-instructions reversed.
Return type
soft_compare
SetMatrixProductState.soft_compare(other)
Soft comparison between gates. Their names, number of qubits, and classical bit numbers must match. The number of parameters must match. Each parameter is compared. If one is a ParameterExpression then it is not taken into account.
Parameters
other (instruction) – other instruction.
Returns
are self and other equal up to parameter expressions.
Return type
bool
validate_parameter
SetMatrixProductState.validate_parameter(parameter)
Instruction parameters has no validation or normalization.
Attributes
condition_bits
Get Clbits in condition.
Return type
List[Clbit]
decompositions
Get the decompositions of the instruction from the SessionEquivalenceLibrary.
definition
Return definition in terms of other basic gates.
duration
Get the duration.
label
Return instruction label
Return type
str
params
return instruction params.
unit
Get the time unit of duration.
