WebNov 29, 2000 · 3. Quantum Mechanics. Four basic principles of quantum mechanics are: (3.1) Physical States. Every physical system is associated with a Hilbert Space, every unit vector in the space corresponds to a possible pure state of the system, and every possible pure state, to some vector in the space. [ 7] (3.2) Physical Quantities. WebMar 27, 2024 · Hilbert space is indeed a big place. In principle, however, Nature manipulates such enormous quantities of data, even for systems containing only a few hundred atoms. It is as if Nature were keeping 2 500 hidden pieces of scratch paper on the side, on which she performs her calculations as the system evolves.
