Quantum doubts: Experts cast shadow on Google's Willow chip "septillion years" claim

Google's quantum lab has introduced Willow, a new chip advancing quantum error correction. It outperforms traditional supercomputers in certain calculations and reduces errors as qubits increase. Willow features 105 qubits with a 0.143% error rate and can maintain quantum data for up to an hour. While promising, practical quantum computers solving real-world problems remain years away and require substantial further investment.
