Given an orthonormal basis, any pure state of a two-level quantum system can be written as a superposition of the basis vectors and , where the coefficient of (or contribution from) each of the two basis vectors is a complex number. This means that the state is described by four real numbers. However only the relative phase between the coefficients of the two basis vectors has any physical meaning (the phase of the quantum system is not directly measurable), so that ther… WebSep 3, 2015 · Understanding the Bloch sphere.

In condensed matter physics, Bloch's theorem states that solutions to the Schrödinger equation in a periodic potential take the form of a plane wave modulated by a periodic function. The theorem is named after the physicist Felix Bloch, who discovered the theorem in 1929.
