**Mountain View, CA –** Google has announced a major breakthrough in quantum computing with its new chip, Willow. The company claims Willow has solved a nearly 30-year-old problem plaguing the field: exponentially decreasing error rates as the number of qubits increases. This achievement, published in *Nature*, marks a significant step towards building practical, large-scale quantum computers.
The core challenge in quantum computing lies in the inherent instability of qubits, the fundamental units of quantum computation. As more qubits are added to a system, errors tend to multiply, hindering performance. Willow, however, demonstrates a novel approach that cuts the error rate in half with each increase in qubit count, achieving what experts call “below threshold” performance.
Beyond error reduction, Willow also showcased its raw computational power. A calculation completed by Willow in under five minutes would take the world’s fastest supercomputer, Frontier, an estimated 10 septillion years. This comparison, based on conservative assumptions according to Google, highlights the potential of quantum computing to tackle previously intractable problems.
Hartmut Neven, founder and lead of Google Quantum AI, emphasized the significance of this achievement, stating that Willow’s performance proves the feasibility of building useful, large-scale quantum computers. The technology has already shown promise in fields like drug development and battery design, and this breakthrough paves the way for even broader applications. Google used the industry-standard random circuit sampling (RCS) benchmark to validate Willow’s performance.
