Google Achieves Breakthrough in Quantum Computing with New Chip
Google achieves breakthrough in quantum computing with new chip. Willow chip features 105 qubits, paving the way for faster and more reliable quantum computing. Google's innovative error-correction method reduces error rates as qubit numbers increase.
The tech giant revealed that it managed to solve a complex computing problem in just five minutes, a task that would have taken a classical computer an incomprehensible amount of time longer than the history of the universe.
Joining the ranks of other tech powerhouses like Microsoft and IBM, Google, under its parent company Alphabet, is delving into quantum computing due to its potential to revolutionise computing speeds, far surpassing the capabilities of current systems. Although the specific math problem solved by Google's Santa Barbara quantum lab may not have immediate commercial applications, the company envisions a future where quantum computers can tackle complex issues in various fields such as medicine, battery chemistry, and artificial intelligence, which are currently beyond the reach of traditional computers.
The breakthrough unveiled by Google revolves around its latest chip named Willow, boasting 105 "qubits," the fundamental units of quantum computers. While qubits are known for their speed, they are also susceptible to errors caused by external factors, even as minor as subatomic particles from cosmic events. The accumulation of errors as more qubits are integrated into a chip can render it no more efficient than a standard computer chip. To address this, scientists have been striving towards quantum error-correction since the 1990s.
In a recent publication in the journal Nature, Google detailed its innovative approach to connecting the qubits in the Willow chip, resulting in reduced error rates as the number of qubits increases. The company claims to be capable of correcting errors in real-time, a crucial development in making quantum machines practical for real-world applications.
Hartmut Neven, the head of Google's Quantum AI unit, expressed confidence in the progress made, stating, "We are past the break-even point." Google's assertion was previously challenged by IBM in 2019, suggesting that a classical computer could solve the same problem in significantly less time. However, Google's latest estimates maintain that even under the most optimistic conditions, a classical computer would require a billion years to achieve comparable results to its newest chip.
While some competitors are producing chips with a higher number of qubits than Google, the company's focus remains on ensuring the reliability of its qubits. Anthony Megrant, the chief architect for Google Quantum AI, highlighted the importance of this approach in an interview, emphasising the company's commitment to producing the most dependable qubits possible.
Google has taken a significant step forward by establishing its dedicated fabrication facility to manufacture the Willow chips, moving away from its previous shared facility at the University of California, Santa Barbara. This new facility is expected to accelerate the production of future chips, which are operated in specialised refrigerators known as cryostats for conducting experiments.
