A state that can have the expected value of the energy change post measurement isn't considered to have an energy, rather an expected energy.

- layer8 2y agoThis is about the energy of the system as described by the Schrödinger equation.
- whatshisface 2y agoIf a measurement changes the expected value of the energy, one or both of the initial and final states won't be time-invariant, and you're talking about the time-invariant Schrodinger equation.
