Until now, the biggest obstacle to building quantum computers with millions of qubits has been one thing: error. Qubits are extremely sensitive and lose information easily.
But Harvard researchers changed the game in an article published this week in the prestigious journal Nature!
Amazing achievement:
The team demonstrated for the first time a true “Fault-Tolerant” system.
Using 448 atomic qubits, they built a system that can not only “detect” errors, but can actively “remove” them and continue computing! This was done using complex sequences of entanglement and “logical magic”.
Why is this news so important?
This is a real “quantum leap”! Until now, fault tolerance was mostly on paper and in theory. This research showed that we have a “conceptually scalable” architecture.
According to the senior researcher, “the big dream that we had for decades, for the first time, is really on the horizon.”
🚀 Looking to the future:
This achievement paves the way to pass the era of noisy and experimental quantum computers (NISQ) and enter the era of powerful and reliable machines. This means solving problems that cannot even be imagined today.
