Researchers at tech giant Google said they mapped out the structure of a molecule 13,000 times faster than the most powerful “supercomputers” available today, achieving the first verifiable quantum advantage. The experiment used Google’s Willow Quantum processor and “quantum echoes,” a technique that uses targeted waves to image an object in detail, according to Google. The technique targets a single qubit, the basic unit of information storage in quantum computing, with a precise signal, causing it to react. The process is then reversed, allowing the researchers to measure the “echo” or signal that bounces back, ... (full story)
