At the edge of absolute zero, researchers at McGill University have coaxed electricity into becoming sound — not the sound of the everyday world, but phonons, the quantum packets of vibration that underpin a largely unexplored frontier of physics. This conversion, long theorized but never practically achieved at such extremes, opens a corridor between two domains of quantum engineering that have historically developed in isolation. The significance is not merely technical: it suggests that the boundaries we draw between different forms of energy and information are, at the deepest levels of na
