Google unveils Willow quantum processor with enhanced capabilities

Google has introduced its new quantum processor, Willow, which features 105 physical qubits and improved error correction capabilities. This advancement allows Willow to perform complex calculations faster than both classical computers and previous quantum models. Willow's design includes a mix of data and measurement qubits, enhancing its ability to maintain coherence and reduce error rates. Researchers tested Willow by solving a challenging problem called random circuit sampling, completing it in minutes, a task that would take classical computers an estimated 10 septillion years. The development of Willow indicates progress in overcoming challenges in quantum computing. Researchers believe this could lead to practical applications in fields like drug design and climate modeling, moving closer to realizing reliable quantum computers.
