@381dbcc7: Phase shifting is indeed possible in quantum mechanics, and it is a crucial aspect of many quantum technologies, such as quantum computing and quantum cryptography. In quantum computing, for example, quantum gates are used to manipulate the phase of a qubit, which allows for the creation of quantum algorithms that can solve certain problems exponentially faster than classical algorithms. In quantum cryptography, phase shifting is used to encode information in the phase of a photon, which makes it impossible for an eavesdropper to intercept the information without disturbing the state of the photon and alerting the receiver.
