WebIn quantum mechanics, the measurement of the z-projection of a particle's spin can be represented by the S. operator. For a spin-1 particle, the S. operator takes the form: 10 S = … WebOct 30, 2010 · Consider a photon flying in the direction of z-axis. Any vector massive particle can have 3 spin states - however one of them requires the z component of momentum to be 0 (particle in rest). Photon can not be in rest, so only 2 spin states remain.

WebSpin-photon coupling has been studied but is challenging because of the small magnetic-dipole moment of a single spin, which limits magnetic-dipole coupling rates to less than 1 kilohertz. Thus, there is a need for more sophisticated techniques for establishing quantum information systems.
