Scientists Observe Macroscopic Quantum Properties in Mechanical Systems

New research introduces "extensive size" and "entangled size" as measures for macroscopic quantum properties, applying them to experimental data. Scientists analyzed micro-mechanical oscillators and diffracting molecules, finding evidence of genuine multipartite entanglement involving 10^5 to 10^7 atoms in recent mechanical superposition states. This work advances understanding of quantum mechanics at larger scales and helps evaluate experimental capabilities in probing these limits.
