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

March 23, 2023

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 theoretical foundations 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.
