WebFeb 4, 2024 · The Hilbert space of a two-level system is just the two-dimensional linear space H 2. Examples of this kind of system are 1 2-spins and two-level atoms. We can define a basis of it by the orthonormal vectors, 0, 1. A pure state of the system would be any unit vector of H 2. WebJan 13, 2024 · Lasing in Two-Level Systems.
