public static void CPhaseShift(
	this QuantumComputer comp,
	int dist,
	RegisterRef target,
	params RegisterRef[] controls
)

public static void CPhaseShift(
	this QuantumComputer comp,
	int dist,
	RegisterRef target,
	params RegisterRef[] controls
)

Parameters

comp: Type: Quantum QuantumComputer
The QuantumComputer instance.

dist: Type: System Int32
Value of k in the angle of phase shift. The angle equals: PI / 2 ^ k.

target: Type: Quantum RegisterRef
The reference to target qubit.

controls: Type: Quantum RegisterRef
The references to control qubits. If there is no control qubit given, the gate is run unconditionally.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type QuantumComputer. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
