AFP: Google on Monday showed off a new quantum computing chip that it said was a major breakthrough that could bring practical quantum computing closer to reality.
A custom chip called “Willow” does in minutes what it would take leading supercomputers 10 septillion years to complete, according to Google Quantum AI founder Hartmut Neven.
“Written out, there is a 1 with 25 zeros,” Neven said of the time span while briefing journalists. “A mind-boggling number.”
Neven’s team of about 300 people at Google is on a mission to build quantum computing capable of handling otherwise unsolvable problems like safe fusion power and stopping climate change.
A quantum computer that can tackle these challenges is still years away, but Willow marks a significant step in that direction, according to Neven and members of his team.
While still in its early stages, scientists believe that superfast quantum computing will eventually be able to power innovation in a range of fields.
Olivier Ezratty, an independent expert in quantum technologies, told AFP in October that private and public investment in the field has totaled around $20 billion worldwide over the past five years.
Regular computers function in binary fashion: they carry out tasks using tiny fragments of data known as bits that are only ever either expressed as 1 or 0.
But fragments of data on a quantum computer, known as qubits, can be both 1 and 0 at the same time — allowing them to crunch an enormous number of potential outcomes simultaneously.
Crucially, Google’s chip demonstrated the ability to reduce computational errors exponentially as it scales up — a feat that has eluded researchers for nearly 30 years.
