NIST: Quantum Bits Can be Self Correcting?

Could be a really big thing,  depending on the context and consequences.  

Error-Prone Quantum Bits Could Correct Themselves, NIST Physicists Show

National Institute of Standards and Technology

Physicists at the U.S. National Institute of Standards and Technology (NIST), the University of Maryland, and the California Institute of Technology have developed an approach that could be used to design self-correcting quantum memory switches. The researchers experimented with a photonic cavity resonator and found that constantly refreshing the supply of photons in the cavity enables the qubit's quantum information to withstand certain amounts and types of noise from the surrounding environment. The new approach accounts for the leakage of photons to the environment. Simon Lieu of the Joint Quantum Institute and the Joint Center for Quantum Information and Computer Science said, "It’s like adding fresh water. Any time the information gets contaminated, the fact that you're pushing in water and cleaning out your pipes dynamically keeps it resistant to damage. This overall configuration is what keeps its steady state strong."
