Ultra nerdy boffins set world record for preventing qubit decoherence to 5 seconds

It's normally in the millisecond range, so 5 whole seconds is a huge advance. I'm confident that suitably nerdy boffins will eventually find a way to preserve qubit coherence indefinitely which will really help to propel quantum computers forward. Perhaps it will eventually be possible to have desktop PCs use quantum technology, and if it ever gets into portable devices, that will be really something, but don't hold your breath for it.

Warning: a large and nerdy brain is required to understand this.


I made a similar post about preserving the quantum state by using two time dimensions (two... whut??) here:
