wy_qcos.transpiler.cmss.circuit.operators.op_shape module

class wy_qcos.transpiler.cmss.circuit.operators.op_shape.OpShape(dims_l=None, dims_r=None, num_qargs_l=None, num_qargs_r=None)

基类：object

Multipartite matrix and vector shape class.

dims_r(qargs=None)

Return tuple of input dimension for specified subsystems.

dims_l(qargs=None)

Return tuple of output dimension for specified subsystems.

property size

Return the combined dimensions of the object.

property num_qubits

Get number of qubits.

Description:

Return number of qubits if shape is N-qubit. If Shape is not N-qubit return None.

property num_qargs

Return a tuple of the number of left and right wires.

property shape

Return a tuple of the matrix shape.

property tensor_shape

Return a tuple of the tensor shape.

property is_square

Return True if the left and right dimensions are equal.

compose(other, qargs=None, front=False)

Return composed OpShape.

参数:

  • other (OpShape)

  • qargs (list | None)

  • front (bool)

validate_shape(shape)

Raise an exception if shape is not valid for the OpShape.

classmethod auto(shape=None, dims_l=None, dims_r=None, dims=None, num_qubits_l=None, num_qubits_r=None, num_qubits=None)

Maxtrix construction.

Description:

Construct TensorShape with automatic checking of qubit dimensions.

返回类型:

OpShape

wy_qcos.transpiler.cmss.circuit.operators.operator module

class wy_qcos.transpiler.cmss.circuit.operators.operator.Operator(data, input_dims=None, output_dims=None)

基类：object

Matrix operator class.

Description:

This represents a matrix operator. Evaluation the equality of the maxtrix.

参数:
property data

The underlying Numpy array.

property dim

Return tuple (input_shape, output_shape).

to_operator()

Convert operator to matrix operator class.

返回类型:

Operator

compose(other, qargs=None, front=False)

Compose self operator with other operator.

Description:

The composition is defined as self * other if front=False or other * self if front=True. If qargs is specified, the composition is performed only on the subsystems specified by qargs.

参数:

  • other (Operator or ScalarOp) -- an operator to compose with.

  • qargs (list | None) -- list of subsystem indices to compose on.

  • front (bool) -- if True compose as self * other, else other * self.

返回:

the composed operator.

返回类型:

Operator

equiv(other, rtol=None, atol=None)

Return True if operators are equivalent.

参数:

  • other (Operator) -- an operator object.

  • rtol (float) -- relative tolerance value for comparison.

  • atol (float) -- absolute tolerance value for comparison.

返回:

True if operators are equivalent up to global phase.

返回类型:

bool

matrix_equal(mat1, mat2, ignore_phase=False, rtol=0, atol=0, props=None)

Test if two arrays are equal.

The final comparison is implemented using Numpy.allclose. See its documentation for additional information on tolerance parameters.

If ignore_phase is True both matrices will be multiplied by exp(-1j * theta) where theta is the first nphase for a first non-zero matrix element |a| * exp(1j * theta).

参数:

  • mat1 (matrix_like) -- a matrix

  • mat2 (matrix_like) -- a matrix

  • ignore_phase (bool) -- ignore complex-phase differences between matrices [Default: False]

  • rtol (double) -- the relative tolerance parameter [Default {}].

  • atol (double) -- the absolute tolerance parameter [Default {}].

  • props (dict | None) -- if not None and ignore_phase is True returns the phase difference between the two matrices under props['phase_difference']

返回:

True if the matrices are equal or False otherwise.

返回类型:

bool

class wy_qcos.transpiler.cmss.circuit.operators.operator.ScalarOp(dims=None, coeff=1.0)

基类：object

Scalar identity operator class.

参数:

  • dims (int | tuple | None)

  • coeff (int | float)

property dim

Return tuple (input_shape, output_shape).

property coeff

Return the coefficient.

input_dims(qargs=None)

Return tuple of input dimension for specified subsystems.

output_dims(qargs=None)

Return tuple of output dimension for specified subsystems.

to_matrix()

Convert to a Numpy matrix.

to_operator()

Convert to an Operator object.

返回类型:

Operator
