Explanation: Google launched the quantum processor ‘Willow,’ advancing quantum computing to solve practical problems. Willow has 105 physical qubits and operates at near absolute zero temperatures (-273.15°C). It features better error correction and faster performance than other quantum computers. The coherence time of Willow’s qubits is around 100 microseconds, improved by error correction. Willow’s architecture enables lower error rates with more qubits. It outperformed classical computers in testing, completing a Random Circuit Sampling task in minutes.
