In quantum mechanics, a two-state system (also known as a two-level system) is a quantum system that can exist in any quantum superposition of two independent (physically distinguishable) quantum states. The Hilbert space describing such a system is two-dimensional. Therefore, a complete basis spanning the space will consist of two independent states. Any two-state syst… WebAug 3, 2024 · In the last line I have simply stated that σz, H = σz, N. I can justify this as follows (and this will segue into my second approach). We could have defined σ − N as the result of the following unitary transformation. UZ = e + iωt ( e e)H σ − N = U † Zσ − HUZ = σ − HUZ = σ − He + iωt σz, N = U † Zσz, HUZ = σz, H.
