Transition Probabilities and Selection Rules
... where J ≡ L+S is the total orbital plus spin angular momentum. The above rules are valid insofar as LS coupling is obeyed (i.e. L and S are good quantum numbers), which is true to the extent that the electrons are nonrelativistic. If LS coupling is violated, then terms may contain admixtures of diff ...

Quantum Teleportation
... To send a key in Quantum Cryptography, simply send photons in one of four polarizations: -45, 0, 45, or 90 degrees. As you know, the receiver can measure, say, whether or not a photon is polarized at 90 degrees and if it is not then be sure than it was polarized at 0 degrees. Similarly the receiver ...
