Computer scientists say they’ve cracked the science behind error-correction in quantum computers thanks to new "4D codes."

Developed by Microsoft, the new codes were revealed in a blog post published June 19 and purport to address the problem of fault tolerance — arguably quantum computing’s biggest bottleneck.
