Quantum Teleportation Channels Opened in Rome and Innsbruck

FEB 01, 1998

Two experiments, using different optical schemes, have transmitted quantum states across a tabletop by means of classical messages and Einstein—Podolsky—Rosen entanglement. Applications will include new tests of the fundamentals of quantum mechanics and quantum computation.

If you’ve heard the reports that teleportation has been achieved, and you’re anxious about the implications for investments in the transportation sector, you can relax and instead look to physics futures for the payoff. Quantum teleportation as it currently exists involves the delicate dismantlement of an individual photon’s quantum state and its reconstruction about a meter away. Although that may sound less exciting than the transport of starship captains from orbit to planet surface it should lead to new tests of the non‐existence of what Albert Einstein, Boris Podolsky and Nathan Rosen called local “elements of reality.”
