Willow

Willow is a state-of-the-art quantum chip designed for researchers and scientists working on quantum computing projects, particularly those focused on quantum error correction and performance. The chip demonstrates error correction and performance that paves the way to a useful, large-scale quantum computer. With 105 qubits, Willow achieves best-in-class performance across quantum error correction and random circuit sampling benchmarks.
Willow's key capabilities include exponential quantum error correction, state-of-the-art performance, and the ability to reduce errors while scaling up the number of qubits. The chip has been tested with ever-larger arrays of physical qubits, showing an exponential reduction in the error rate. This historic accomplishment is known in the field as “below threshold” — being able to drive errors down while scaling up the number of qubits.
Researchers and scientists working on quantum computing projects, particularly those focused on quantum error correction and performance, get the most value from Willow. The chip's ability to demonstrate a first "useful, beyond-classical" computation on today's quantum chips that is relevant to a real-world application makes it an essential tool for those in the field. With its state-of-the-art performance and error correction capabilities, Willow is ideal for researchers looking to unlock new possibilities in quantum computing.
