Google’s quantum computing lab just achieved a major milestone. On Monday, the company revealed that its new quantum computing chip, Willow, is capable of performing a computing challenge in less than five minutes — a process Google says would take one of the world’s fastest supercomputers 10 septillion years, or longer than the age of the universe.

Along with more powerful performance, researchers also found a way to reduce errors, something Google calls “one of the greatest challenges in quantum computing.” Instead of bits, which represent either 1 or 0, quantum computing uses qubits, a unit that can exist in multiple states at the same time, such as 1, 0, and anything in between.

As noted by Google, qubits are prone to errors because they “have a tendency to rapidly exchange information with their environment.” However, Google’s researchers discovered a way to reduce errors by introducing more qubits to a system and were able to correct them in real time. Their findings were published in Nature.

“This historic accomplishment is known in the field as ‘below threshold’ — being able to drive errors down while scaling up the number of qubits,” Google Quantum AI founder Hartmut Neven writes on Google’s blog. “You must demonstrate being below threshold to show real progress on error correction, and this has been an outstanding challenge since quantum error correction was introduced by Peter Shor in 1995.”

Willow, which has 105 qubits, “now has best-in-class performance,” according to Neven. Microsoft, Amazon, and IBM are working on quantum computing systems of their own.

Google’s next goal is to perform a first “useful, beyond-classical” computation that is both “relevant to a real-world application” and one that typical computers can’t achieve. Going forward, Neven says quantum technology will be “indispensable” for collecting AI training data, eventually helping to “discover new medicines, designing more efficient batteries for electric cars, and accelerating progress in fusion and new energy alternatives.”
