NoiseTransformer

class NoiseTransformer

Bases: object

Transforms one quantum channel to another based on a specified criteria.

Methods

channel_matrix_representation	We convert the operators to a matrix by applying the channel to the four basis elements of the 2x2 matrix space representing density operators; this is standard linear algebra
compute_P	This method creates the matrix P in the f(x) = 1/2(x*P*x)+q*x representation of the objective function :param As: list of symbolic matrices repersenting the channel matrices :type As: list
compute_channel_operation	Given a quantum state’s density function rho, the effect of the channel on this state is: rho -> sum_{i=1}^n E_i * rho * E_i^dagger
compute_q	This method creates the vector q for the f(x) = 1/2(x*P*x)+q*x representation of the objective function :param As: list of symbolic matrices repersenting the quadratic program :type As: list :param C: matrix representing the the constant channel matrix :type C: matrix
fidelity	Calculates channel fidelity
flatten_matrix	param m The matrix to flatten
generate_channel_matrices	Generate symbolic channel matrices.
generate_channel_quadratic_programming_matrices	Generate matrices for quadratic program.
get_const_matrix_from_channel	Extract the numeric constant matrix.
get_matrix_from_channel	Extract the numeric parameter matrix.
operator_circuit	Converts an operator representation to noise circuit.
operator_matrix	Converts an operator representation to Kraus matrix representation
prepare_channel_operator_list	Prepares a list of channel operators.
prepare_honesty_constraint	Prepares the honesty constraint.
solve_quadratic_program	Solve the quadratic program optimization problem.
transform_by_given_channel	Transform by by quantum channels.
transform_by_operator_list	Transform input Kraus operators.
