‘Quantum Internet’ Inches Closer With Advance in Data Teleportation

Their research, unveiled this week with a paper published in the science journal Nature, demonstrates the power of a phenomenon that Albert Einstein once deemed impossible. Quantum teleportation — what he called “spooky action at a distance” — can transfer information between locations without actually moving the physical matter that holds it.

“This not only means that the quantum computer can solve your problem but also that it does not know what the problem is,” said Tracy Eleanor Northup, a researcher at the University of Innsbruck’s Institute for Experimental Physics who is also exploring quantum teleportation. “It does not work that way today. Google knows what you are running on its servers.”

Although it cannot move objects from place to place, it can move information by taking advantage of a quantum property called “entanglement”: A change in the state of one quantum system instantaneously affects the state of another, distant one.

“After entanglement, you can no longer describe these states individually,” Dr. Northup said. “Fundamentally, it is now one system.”
