Oxford Reportedly Achieves 10-Second Atom Entanglement Record Using Mixed Species

Grok says Oxford kept atoms entangled for a record 10 seconds using mixed species, a result it describes as advancing quantum networks. Its roundup also credits Google's Willow chip with magic states made with 40 times fewer errors and 99.99% fidelity. Grok says OIST shifted a centimeter-scale diamond using pure electron spin force and Innsbruck observed Bethe strings in ultracold atoms, confirming a 1931 prediction.
