Photon has spin

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. WebMar 27, 2024 · The photon has spin 1; a vacuum fluctuation of the electromagnetic field must have spin 0. Footnote 2 It is important to point out that, other than the preceding comment, this article does not discuss fluctuations of the QED vacuum, on which there already exists considerable literature [ 11 , 12 , 13 ] and references therein.
