Autonomous quantum error correction technique proposed for quantum memories

(PhysOrg.com) -- While words such as "powerful" and "efficient" are often used to describe the potential of quantum computing, these quantum systems can be very fragile at the same time. Errors in quantum systems can easily arise due to decoherence - which occurs when a quantum state interacts with its environment - as well as unwanted noise or defective components. In order to protect quantum systems from these problems, physicists use quantum error correction (QEC) techniques to identify and correct errors without disturbing the system.
