In quantum mechanics and computing, the Bloch sphere is a geometrical representation of the pure state space of a two-level quantum mechanical system, named after the physicist Felix Bloch.

The mathematical concept of a Hilbert space generalizes the notion of Euclidean space. It extends the methods of Euclidean geometry and calculus from the two-dimensional Euclidean plane and three-dime
Bloch sphere
…mechanical system (qubit), named after the physicist Felix Bloch. Mathematically each quantum mechanical system is associated with a separable complex Hilbert space H . A pure state of a quantum system is represented by a non-zero vector ψ in H . The vectors ψ and λ ψ (with λ a non-zero complex number) represent…
