In quantum mechanics and computing, the Bloch sphere is a geometrical representation of the pure state space of a two-level quantum mechanical system (qubit), named after the physicist Felix Bloch. Quantum mechanics is mathematically formulated in Hilbert space or projective Hilbert space. The pure … See more Given an orthonormal basis, any pure state $${\displaystyle \psi \rangle }$$ of a two-level quantum system can be written as a superposition of the basis vectors $${\displaystyle 0\rangle }$$ and We also know from … See more Given a pure state $${\displaystyle \alpha \left \uparrow \right\rangle +\beta \left \downarrow \right\rangle =\left \nearrow \right\rangle }$$ See more A useful advantage of the Bloch sphere representation is that the evolution of the qubit state is describable by rotations of the Bloch sphere. … See more Consider an n-level quantum mechanical system. This system is described by an n-dimensional Hilbert space Hn. The pure state space is by definition the set of 1-dimensional rays of … See more Formulations of quantum mechanics in terms of pure states are adequate for isolated systems; in general quantum mechanical … See more • Atomic electron transition • Gyrovector space • Poincaré sphere (optics) • Versors • Specific implementations of the Bloch sphere are enumerated under the qubit article.
