Story summary

Harvard researchers have developed a fault-tolerant quantum system that detects and corrects errors using 448 atomic qubits.
Published in Nature, the study shows the architecture suppresses errors below a threshold and uses quantum teleportation.
The project involves Harvard University and Massachusetts Institute of Technology (MIT) researchers along with other institutions.
Mikhail Lukin, co-director, says this progress makes functional quantum computing within reach.
