WebDec 1, 2024 · The first postulate summarizes this situation. Postulate 1: The state of a quantum system at a given moment is completely defined by giving its state vector (ket), \left \varphi \right\rangle . The state vector is an element of the Hilbert space \mathcal {H}, which also is called the state space. Remarks: 1. WebPostulate 1: The wavefunction attempts to describe a quantum me-chanical entity (photon, electron, x-ray, etc.) through its spatial location and time dependence, i.e. the wavefunction is in the most general sense dependent on time and space: = (x;t) The state of a quantum mechanical system is completely speci ed by the wavefunction (x;t).
