Complex phase, or phase shift, refers to a change in the phase of a complex number. It is usually expressed in degrees, which measure the amount of rotation of the phase vector from its original position.

Complex phase has many applications in engineering and physics, from signal analysis in communications systems to quantum computing. In the communications field, phase shift is used to adjust the amplitude, frequency, and other characteristics of a signal to alter its propagation characteristics. In quantum computing, phase shift is used to quantum-encrypt a string of bits.

Phase shift is also useful in mechanical engineering. It is used to control the flow of fluid around an object, to reduce the drag on a body moving through air or water, or to control the vibration of a structure.

In mathematics, complex phase is used to represent a vector in higher-dimensional space, where the direction of the vector can be determined by the angle of its phase. In polar coordinates, this angle is measured in radians.

In acoustics, phase shift can be used to combine different audio signals. For example, by adjusting the phase of two signals, a sound engineer can create a complex sound that is composed of both signals.

Finally, complex phase can also be used to describe certain kinds of physical systems, such as an electrical circuit. By altering the phase of the components in an electrical circuit, the current oscillations in the circuit can be altered, which can be used to control the functionality of the circuit.
