How to get Bloch sphere Cartesian coordinates from density matrix
WebApr 7, 2024 · The reason why I prefer this notation is that I want to keep Bloch sphere formalism (e.g. 0 ≤ ( π − θ) ≤ π constrant that is true for ψ ⊥ presented here). Note that: ψ ψ ⊥ = cos θ 2 sin θ 2 − sin θ 2 cos θ 2 = 0 By doing the same calculations we can obtain for ϕ = γ ψ + δ ψ ⊥ = α 0 + β 1 : WebThe surface of the Bloch sphere is a two-dimensional space, which represents the observable state space of the pure qubit states. This state space has two local degrees … how to activate rockstar key

A 180-degree rotation around X+Z swaps points on the X axis to the Z axis (and vice versa), and negates points on the Y axis. The same thing is true of rotating 90 degrees around Y then 180 degrees around X.
