GatesExtension PhaseScale Method A Sandcastle Documented Class Library

Adds a global phase on the registers' state. The operation is represented by the unitary matrix:

Namespace: Quantum.Operations
Assembly: Quantum (in Quantum.dll) Version: (

public static void PhaseScale(
	this QuantumComputer comp,
	double gamma,
	RegisterRef target,
	Nullable<RegisterRef> control = null


Type: Quantum QuantumComputer
The QuantumComputer instance.
Type: System Double
The phase that is added to the registers' state.
Type: Quantum RegisterRef
The reference to target qubit.
control (Optional)
Type: System Nullable RegisterRef 
Optional argument. If given, the method performs controlled gate operation. Destribes the reference to control qubit.

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).
