Submission + - Physicists show self-correcting quantum computers are theoretically possible (phys.org)

InfiniteZero writes: From the article at phys.org:

Using exotic components such as color codes, new phases of quantum matter, and extra dimensions, a team of physicists has shown that it's theoretically possible to construct a quantum computer that has the ability to correct itself whenever an error occurs.

"The greatest significance of our work is showing that self-correcting quantum computing at a finite temperature is not impossible as a matter of principle," physicist Héctor Bombin told Phys.org. Bombin was at MIT in Cambridge, Massachusetts, while performing the study and is currently at the Perimeter Institute in Waterloo, Ontario. "In fact, the original motivation came from claims to the contrary by other authors. We provide explicit constructions that can be checked directly, without numerical simulations."
