Is Your Quantum Computer Faking It? Physicists Unveil a “Quantum Lie Detector”

A new test confirms deep quantum behavior in large-scale systems, including multipartite correlations. Is it possible to verify whether a large quantum system genuinely follows the unusual principles of quantum mechanics, or merely appears to do so? In a groundbreaking experiment, physicists from Leiden, Beijing, and Hangzhou have answered that question. At the heart of [...]
