qiskit.providers.aer.library.SetMatrixProductState¶

class
SetMatrixProductState
(state)[código fonte]¶ Set the matrix product state of the simulator
Create new instruction to set the matrix product state of the simulator.
 Parâmetros
state (Tuple[List[Tuple[np.array[complex_t]]]], List[List[float]]) – A matrix_product_state.
Nota
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.

__init__
(state)[código fonte]¶ Create new instruction to set the matrix product state of the simulator.
 Parâmetros
state (Tuple[List[Tuple[np.array[complex_t]]]], List[List[float]]) – A matrix_product_state.
Nota
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
__init__
(state)Create new instruction to set the matrix product state of the simulator.
add_decomposition
(decomposition)Add a decomposition of the instruction to the SessionEquivalenceLibrary.
assemble
()Assemble a QasmQobjInstruction
broadcast_arguments
(qargs, cargs)Validation of the arguments.
c_if
(classical, val)Add classical condition on register or cbit classical and value val.
copy
([name])Copy of the instruction.
inverse
()Invert this instruction.
Return True .IFF.
mirror
()DEPRECATED: use instruction.reverse_ops().
qasm
()Return a default OpenQASM string for the instruction.
repeat
(n)Creates an instruction with gate repeated n amount of times.
For a composite instruction, reverse the order of subinstructions.
soft_compare
(other)Soft comparison between gates.
validate_parameter
(parameter)Instruction parameters has no validation or normalization.
Attributes
Get the decompositions of the instruction from the SessionEquivalenceLibrary.
Return definition in terms of other basic gates.
Get the duration.
Return instruction label
return instruction params.
Get the time unit of duration.

add_decomposition
(decomposition)¶ Add a decomposition of the instruction to the SessionEquivalenceLibrary.

assemble
()¶ Assemble a QasmQobjInstruction

broadcast_arguments
(qargs, cargs)¶ Validation of the arguments.
 Parâmetros
qargs (List) – List of quantum bit arguments.
cargs (List) – List of classical bit arguments.
 Yields
Tuple(List, List) – A tuple with single arguments.
 Levanta
CircuitError – If the input is not valid. For example, the number of arguments does not match the gate expectation.

c_if
(classical, val)¶ Add classical condition on register or cbit classical and value val.

copy
(name=None)¶ Copy of the instruction.
 Parâmetros
name (str) – name to be given to the copied circuit, if None then the name stays the same.
 Retorna
 a copy of the current instruction, with the name
updated if it was provided
 Tipo de retorno

property
decompositions
¶ Get the decompositions of the instruction from the SessionEquivalenceLibrary.

property
definition
¶ Return definition in terms of other basic gates.

property
duration
¶ Get the duration.

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.)
 Retorna
a fresh instruction for the inverse
 Tipo de retorno
 Levanta
CircuitError – if the instruction is not composite and an inverse has not been implemented for it.

is_parameterized
()¶ Return True .IFF. instruction is parameterized else False

property
label
¶ Return instruction label
 Tipo de retorno
str

mirror
()¶ DEPRECATED: use instruction.reverse_ops().
 Retorna
 a new instruction with subinstructions
reversed.
 Tipo de retorno

property
params
¶ return instruction params.

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
(n)¶ Creates an instruction with gate repeated n amount of times.
 Parâmetros
n (int) – Number of times to repeat the instruction
 Retorna
Containing the definition.
 Tipo de retorno
 Levanta
CircuitError – If n < 1.

reverse_ops
()¶ For a composite instruction, reverse the order of subinstructions.
This is done by recursively reversing all subinstructions. It does not invert any gate.
 Retorna
 a new instruction with
subinstructions reversed.
 Tipo de retorno

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.
 Parâmetros
other (instruction) – other instruction.
 Retorna
are self and other equal up to parameter expressions.
 Tipo de retorno
bool

property
unit
¶ Get the time unit of duration.

validate_parameter
(parameter)¶ Instruction parameters has no validation or normalization.
