'Quantum discord' From https://news.ycombinator.com/context?id=39954180 and [2] https://en.wikipedia.org/wiki/Quantum_discord : > FWIU, there are various types of quantum entropy; entanglement and non-entanglement entropy. Quantum discord [2]: >> In quantum information theory, quantum discord is a measure of nonclassical correlations between two subsystems of a quantum system. It includes correlations that are due to quantum physical effects but do not necessarily involve quantum entanglement. 'Nonquantum entanglement' From https://news.ycombinator.com/context?id=40302396 : > "Nonquantum…

"Quantum Gravity Gets a New Test" (2024) https://physics.aps.org/articles/v17/65 : > As the pendulums oscillate, they change the size and therefore the resonant wavelength of each cavity. This change can be detected by shining laser light into the cavities and then measuring the intensity of the resulting interference pattern. FWIU there is more information in light intensity; from https://news.ycombinator.com/item?id=37226160 : > > The work, led by Xiaofeng Qian, assistant professor of physics at Stevens and reported in the August 17 online issue of Physical Review Research, also proves for…
