Manipulation of Photonic Orbital Angular Momentum for Quantum Information Processing

摘要: More than a century ago, pioneeringworks carried out by Poynting (1909) and other physicists have provided the evidence of validity Marxwell equations for an electromagnetic field, showing how beam light carries energy momentum, both in linear angular components. In particular momentum light, related to generator rotations quantum mechanics, has been typically associated with its polarization, more specifically circular polarization An optical traveling positive direction z axis that is circularly polarized, z-component content σ = ±h per photon, which if left-handed negative it right-handed. This not just formal property, but very concrete one can significant mechanical effects as example observable induced rotation absorption amaterial particle Beth (1936); Friese et al. (1998)
