John Clarke, Michel H. Devoret und John M. Martinis erhalten den Nobelpreis für Physik 2025 für Experimente, die Quantentunneln in makroskopischen Schaltkreisen demonstrieren. Ihre Arbeit aus den 1980er Jahren legte den Grundstein für supraleitende Quantencomputer. Die Preisträger äußerten große Überraschung über die Auszeichnung.
An international team of physicists has found that quantum collapse models, potentially linked to gravity, introduce a minuscule uncertainty in time itself. This sets a fundamental limit on clock precision, though far below current detection levels. The research, published in Physical Review Research, explores ties between quantum mechanics and gravity.

Irish mathematician William Rowan Hamilton developed a framework in the 1820s and 1830s that linked the paths of light rays and moving particles, an idea that later proved crucial to quantum mechanics. Born 220 years ago, Hamilton's work, including carving a formula on Dublin's Broome Bridge in 1843, built on earlier physics but revealed deeper connections only understood a century later. This insight helped shape modern theories of wave-particle duality.
Scientists have developed highly precise ultracold atomic clocks that could detect how quantum physics influences the flow of time. By cooling atoms to near absolute zero, these devices aim to measure subtle time variations predicted by quantum theory. The research, published in Nature Communications, opens new avenues for testing fundamental physics.
