This module contains classes and functions for Operator arithmetic.

Constructor Functions

adjoint(fn[, lazy])	Create the adjoint of an Operator or a function that applies the adjoint of the provided function.
ctrl(op, control[, control_values, work_wires])	Create a method that applies a controlled version of the provided op.
exp(op[, coeff, num_steps, id])	Take the exponential of an Operator times a coefficient.
sum(*summands[, do_queue, id, lazy])	Construct an operator which is the sum of the given operators.
pow(base[, z, lazy, do_queue, id])	Raise an Operator to a power.
prod(*ops[, do_queue, id, lazy])	Construct an operator which represents the generalized product of the operators provided.
s_prod(scalar, operator[, lazy, do_queue, id])	Construct an operator which is the scalar product of the given scalar and operator provided.

Symbolic Classes

Adjoint([base, do_queue, id])	The Adjoint of an operator.
CompositeOp(*operands[, do_queue, id])	A base class for operators that are composed of other operators.
Controlled(base, control_wires[, …])	Symbolic operator denoting a controlled operator.
ControlledOp(base, control_wires[, …])	Operation-specific methods and properties for the Controlled class.
Evolution(generator[, param, num_steps, …])	Create an exponential operator that defines a generator, of the form \(e^{-ix\hat{G}}\)
Exp(base[, coeff, num_steps, do_queue, id])	A symbolic operator representing the exponential of a operator.
Pow([base, z, do_queue, id])	Symbolic operator denoting an operator raised to a power.
Prod(*operands[, do_queue, id])	Symbolic operator representing the product of operators.
Sum(*operands[, do_queue, id])	Symbolic operator representing the sum of operators.
SProd(scalar, base[, do_queue, id])	Arithmetic operator representing the scalar product of an operator with the given scalar.
SymbolicOp(base[, do_queue, id])	Developer-facing base class for single-operator symbolic operators.
ScalarSymbolicOp(base, scalar[, do_queue, id])	Developer-facing base class for single-operator symbolic operators that contain a scalar coefficient.

Controlled Operator Classes

ControlledQubitUnitary(U, control_wires, …)

Apply an arbitrary fixed unitary to wires with control from the control_wires.

Decompositions

ctrl_decomp_zyz(target_operation, control_wires)	Decompose the controlled version of a target single-qubit operation
ctrl_decomp_bisect(target_operation, …)	Decompose the controlled version of a target single-qubit operation
