How does the phase of an eigenstate evolve over time according to Schrodinger's equation?
According to Schrödinger's equation, the phase of an eigenstate evolves over time in a deterministic manner. The equation, named after Austrian physicist Erwin Schrödinger, is a fundamental equation in quantum mechanics that describes the time evolution of a quantum system. It is a partial differential equation that relates the time derivative of the wave function

How does the energy measurement of a superposition state differ from that of an eigenstate?
In the field of quantum information, the measurement of energy in a superposition state differs from that of an eigenstate. To understand this difference, we need to consider the concepts of superposition and eigenstates, as well as the mathematical framework of quantum mechanics. In quantum mechanics, a superposition state is a state in which a
