Just as overlapping ripples on a pond can amplify or cancel each other out, waves of many kinds—including light, sound and atomic vibrations—can interfere with one another. At the quantum level, this kind of interference powers high-precision sensors and could be harnessed for quantum computing. /news/2025-08-powerful-quantum-paves-phonon-based.html Condensed Matter Quantum Â鶹ÒùÔºics Mon, 11 Aug 2025 14:39:04 EDT news674141941 Researchers at Tampere University and their collaborators from Germany and India have experimentally confirmed that angular momentum is conserved when a single photon is converted into a pair—validating a key principle of physics at the quantum level for the first time.
