Mountain View, CA – Google has announced a major breakthrough in quantum computing with its new chip, Willow. This 105-qubit processor demonstrates a significant reduction in error rates as the number of qubits increases – a feat known as “below threshold” and considered crucial for building large-scale, practical quantum computers. This achievement, published in *Nature*, marks a substantial step towards commercially viable quantum technology.

Willow’s error correction capabilities were tested using increasingly large arrays of qubits, consistently halving the error rate with each increase. This exponential reduction signifies a landmark achievement in overcoming a major hurdle in quantum computing: the tendency for errors to multiply as the system scales. The chip also boasts real-time error correction, crucial for completing complex computations before errors overwhelm the system.

The chip’s computational power was demonstrated using the random circuit sampling (RCS) benchmark. Willow completed a calculation in under five minutes that would take the world’s fastest supercomputers an estimated 10 septillion years, highlighting its potential to tackle problems far beyond the capabilities of classical computers.

“This is the most convincing prototype for a scalable logical qubit built to date,” said [Google representative’s name and title]. “It’s a strong sign that useful, very large quantum computers can indeed be built.”

Google emphasized that Willow’s superior performance stems from a holistic approach to system engineering, optimizing all aspects of the chip’s design and fabrication. The company also stressed the importance of focusing on both quantity and quality of qubits, achieving best-in-class performance across both quantum error correction and RCS benchmarks.

While RCS currently lacks direct real-world applications, Google believes Willow paves the way for future computations that are both beyond the reach of classical computers and relevant to practical problems in fields like medicine, energy, and artificial intelligence. The company is inviting researchers to collaborate using its open-source software and educational resources. This breakthrough represents a major step forward in the quest to build commercially relevant quantum computers capable of revolutionizing various industries.
