A team of Scottish and *South African *researchers have provided the
world's first experimental demonstration of something called entanglement
swapping
<https://phys.org/news/2007-10-entanglement-swapping-quantum.html>, which
allowed them to transmit the orbital angular momentum
<https://en.wikipedia.org/wiki/Orbital_angular_momentum_of_light> (OAM)
of photons of light further than before.
