(June 5, 2015) A team
of scientists have taken quantum teleportation – a method of communicating
information from one location to another without having to physically move it –
to a higher level by using certain high-dimensional states (which they dubbed
“donut” states) for teleportation. Stony Brook University physicist Tzu-Chieh
Wei, PhD, and colleagues nationally demonstrated that their method works, is more
reliable than previous teleportation schemes, and could be a stepping stone
toward building a quantum communications network. Their findings appear in
Nature Communications.
