Google has unveiled its latest quantum chip, Willow, marking a significant milestone in quantum computing. This state-of-the-art chip demonstrates exceptional performance across various metrics, enabling two major achievements that bring us closer to the realization of large-scale quantum computers.
Exponential Error Reduction
One of Willow’s standout features is its ability to reduce errors exponentially as more qubits are used. This breakthrough addresses a long-standing challenge in quantum error correction, a field pursued for nearly 30 years. By scaling up from a grid of 3×3 encoded qubits to larger arrays, Willow has successfully halved the error rate each time, achieving an exponential reduction in errors.
Benchmark Performance
Willow’s performance on standard benchmark computations is nothing short of astonishing. It completed a computation in under five minutes that would take one of today’s fastest supercomputers 10 septillion years. This achievement highlights Willow’s computational power and underscores the potential of quantum computing to solve complex problems beyond the reach of classical computers.

State-of-the-Art Fabrication
Fabricated in Google’s state-of-the-art facility in Santa Barbara, Willow boasts 105 qubits and best-in-class performance across key system benchmarks. The chip’s design and fabrication process focus on quality, ensuring that all components work seamlessly together to maximize system performance.
Future Prospects
The introduction of Willow is a major step forward in Google’s long-term roadmap for quantum computing. As the first system to demonstrate being “below threshold” in error correction, Willow paves the way for practical, commercially relevant quantum algorithms. This advancement brings us closer to running real-world applications that cannot be replicated on conventional computers.
Google invites researchers, engineers, and developers to join this journey by exploring their open-source software and educational resources. With Willow, the future of quantum computing looks promising, offering new opportunities for scientific discovery and technological innovation.
