WebThe dynamics can be interpreted as a special kind of correlation involving the spatial components of the Bloch polarization vectors of the constituent entangled spin-1/2 particles. 1. Introduction. Entanglement is an important feature of quantum mechanics that is useful in the area of “quantum computing and information.”
WebMay 29, 2024 · Ideally, one would think that the six free parameters correspond to two sets of three parameters, so that we could represent a two-qubit pure state using two Bloch spheres. We could look at the reduced density matrix for each qubit, calculate the coordinates of each qubit on the Bloch sphere, and be done.

WebDec 23, 2024 · They can be anywhere within the Bloch sphere and must reside on the surface (if the state is pure). The Bernoulli line (red) still determines the outcomes of the shots. The projection of the quantum state onto the Bernoulli line determines the location of the geometrical blue dot which represents the Bernoulli probability parameter, p. WebThis present thesis araised as theorical proposal for the reconstruction of density matrix of a single electron spin qubit using spin polarized transport. This model consists in a composed system for quantum dot attached to the ferromagnetics reservoir with magnetic field along 𝑥𝑦 plane on the Bloch sphere.
