It’s not quite as wondrous as Scotty’s beaming the crew back to the Starship Enterprise, but a team from the Joint Quantum Institute (JQI) at the University of Maryland and the University of Michigan has succeeded in teleporting a quantum state directly from one atom to another over a substantial distance. Such a capability is necessary for workable quantum information systems because they will require memory storage at both the sending and receiving ends of the transmission. In an article published January 23 in the journal Science, the researchers report that, by using their protocol, atom-to-atom teleporting can be recovered with perfect accuracy about 90 percent of the time—and that figure can be improved. According to group leader, Christopher Monroe of JQI and the University of Maryland Department of Physics, “Our System has the potential to form the basis for a large-scale “quantum repeater” that can network quantum memories over vast distances. Moreover, our methods can be used in conjunction with quantum bit operations to create a key component needed for quantum computation.” A quantum computer could perform certain tasks, such as encryption-related calculations and searches of giant databases considerably faster than conventional machines. The effort to divide a working model is a matter of intense effort worldwide.Learn further details from the University of Maryland website.
