Google's Quantum Leap with Willow Chip
Google has introduced a new quantum chip called Willow, which is claimed to be a significant advancement towards achieving quantum supremacy. This chip boasts an upgrade from the previous Sycamore model, moving from 67 to 105 qubits, allowing for better retention of quantum properties. A benchmark test highlighted its capabilities, showing that Willow could perform a specific computing task in just five minutes, whereas the best supercomputer would take an unfathomable amount of time—10 septillion years. The key achievement with Willow is its error correction capabilities, demonstrating that it has reached a critical quantum error correction threshold, enhancing its practical application potential in future quantum computing developments.
