Zeilinger is an experimental master of photon manipulation. Zeilinger’s group has already demonstrated that it can send and receive single photons over distances much longer than the 10 kilometers from the lab to the mirror in the vineyard and back. In 2012, they successfully sent entangled photons over 143 kilometers, between La Palma and Tenerife in the Canary Islands. And Zeilinger has also spent decades conducting improved versions of Aspect’s Bell experiments, verifying the existence of quantum nonlocality with enormous experimental precision.
