How does Willow's error correction mechanism work, and how does it address previous limitations in scaling up quantum processors?

Willow's error reduction is achieved through a real-time error correction system using encoded qubits to create more stable 'logical qubits'. As the number of physical qubits increases, the error rate decreases exponentially, overcoming a major hurdle that has hindered quantum computing progress for nearly 30 years. This advancement allows for the development of larger, more powerful quantum processors.

What is the fundamental difference between classical and quantum computers, and what are the current limitations of quantum computing?

Classical computers are limited by their binary bits (0 or 1), while quantum computers use qubits that can represent multiple values simultaneously, enabling faster calculations but also higher error rates. Current quantum computers, though improving, still have error rates too high for many complex calculations. Google's recent advance in error correction using a surface code is a significant step forward.
