In the HaPPY code and other holographic error-correcting schemes that have been discovered, everything inside a region of the interior space-time called the “entanglement wedge” can be ...

The error-correcting scheme selected was an Extended Golay code (24, 12, 8), which, interestingly, was also used for image transmission by the NASA Voyager 1 and 2 missions.

Color codes 3,4,5,6,7 are a family of topological quantum error-correcting codes 8,9,10,11 with impressive versatility 12,13,14 for performing fault-tolerant logic gates 15,16,17.

Our codes can handle errors that scale like L 2 (L × L) – a significant improvement. Dr. Dominic Williamson, Study Lead Author, University of Sydney Nano Institute ...

To circumvent this difficulty, Markus Müller's research group has established a method that allows the quantum computer to switch back and forth between two correction codes in an error-tolerant ...

The new technique, outlined in a preprint on arXiv, comes from the same family of error-correction approaches as the surface code. But while each qubit in the surface code is connected to four others, ...

As a bonus, researchers hope holographic space-time might also point the way to scalable quantum computing, fulfilling the long-ago vision of Shor and others. “Space-time is a lot smarter than us,” ...
