Doubling a qubit’s life, researchers prove a key theory of quantum physics

Posted by in category: quantum physics

Researchers at Yale have for the first time, using a process known as quantum error correction, substantially extended the lifetime of a quantum bit—a long-sought-after goal and one of the trickiest challenges in the field of quantum physics.

Led by Yale’s Michael Devoret, the experiment proves—decades after its were proposed—that quantum error correction works in practice. Quantum error correction is a process designed to keep quantum information intact for a period of time longer than if the same information were stored in hardware components without any correction.

The results were published March 22 in Nature.
