World record for the entanglement of twisted light quanta

The Vienna research team led by Anton Zeilinger has achieved a new milestone in the history of quantum physics: The scientists were able to generate and measure the entanglement of the largest quantum numbers to date. To this end, the researchers developed a new method for entangling single photons which gyrate in opposite directions. This result is a first step towards entangling and twisting even macroscopic, spatially separated objects in two different directions. The researchers at the Vienna Center for Quantum Science and Technology (VCQ), situated at the University of Vienna, and the Institute for Quantum Optics and Quantum Information (IQOQI) at the Austrian Academy of Sciences have were able to get their pioneering results published in the current issue of the renowned scientific journal Science.
