Questions and answers designated by tag: Normalization

The normalization of the quantum state condition corresponds to adding up the probabilities (squares of modules of quantum superposition amplitudes) to 1?

Sunday, 05 May 2024 by dkarayiannakis

In the realm of quantum mechanics, the normalization of a quantum state is a fundamental concept that plays a important role in ensuring the consistency and validity of quantum theory. The normalization condition indeed corresponds to the requirement that the probabilities of all possible outcomes of a quantum measurement must sum to unity, which is
