Ultracold molecules hold promise for quantum computing

Researchers have taken an important step toward the long-sought goal of a quantum computer, which in theory should be capable of vastly faster computations than conventional computers, for certain kinds of problems. The new work shows that collections of ultracold molecules can retain the information stored in them, for hundreds of times longer than researchers have previously achieved in these materials.These two-atom molecules are made of sodium and potassium and were cooled to temperatures ju
