World Record for the Entanglement of Twisted Light Quanta
A research team led by the University of Vienna has developed a new method for entangling single photons that gyrate in opposite directions. This is the first step towards entangling and twisting even macroscopic, spatially separated objects in two different directions, according to the team. The findings of this study have been published in the journal Science.
The team, which includes Anton Zeilinger, has taken the first steps towards testing quantum mechanical entanglement with rotating photons. “In our experiment, we entangled the largest quantum numbers of any kind of particle ever measured,” Zeilinger said.
