CHICAGO (Reuters) – U.S. physicists have coaxed tiny artificial atoms into communicating in an advance that may lead to super-fast quantum computers, the researchers said on Wednesday.
Quantum computers hold the promise of being enormously powerful, capable of solving in seconds problems that take today’s fastest machines years to crack.
So far, physicists have worked mostly on developing the most basic of elements that can store information known as quantum bits, or qubits.
But a series of papers in the journal Nature suggest researchers have found a way to get these qubits to communicate over a distance, for instance, across a computer chip.
In the past, the best qubits could do was talk to neighboring qubits, much like the childhood game of telephone.
But researchers from Yale University have found a way to move information stored in a stationary quantum bit via a microwave photon to another stationary quantum bit on the same chip.
