IT has been suggested that co-ordinates should be represented in the quantum theory by operators analogous to those which represent orbital angular momentum 1.

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...

Six photons: physicists in China have entangled photons in terms of polarization, position and orbital angular momentum. (Courtesy: iStock/CopterAnansak) Physicists in China have fully entangled 18 ...

a.The architecture of the all-optical CNN for OAM-mediated machine learning, which can be applied to encode a data-specific image into OAM states. The photonic neural network comprises a trainable ...
