Physicists have developed a new method to detect quantum entanglement by measuring anomalous heat flow, which can serve as a non-destructive thermometer for quantumness, leveraging the unique properties of quantum mechanics to potentially improve quantum computing and explore gravity's quantum nature.
Researchers at Kyoto and Hiroshima Universities have developed a new method to measure the W state of three entangled photons, enabling more efficient quantum state identification and advancing quantum communication and computing technologies.
University of Vermont physicists have solved a 90-year-old problem by developing an exact quantum model of damped harmonic oscillators, akin to vibrating guitar strings at the atomic scale, using advanced mathematical techniques that could lead to ultra-precise quantum measurements and sensors.
CU Boulder scientists developed a novel quantum device using cold atoms and lasers to measure 3D acceleration simultaneously, a breakthrough that could enhance navigation systems for various vehicles. The device employs a Bose-Einstein Condensate and AI-driven laser adjustments, and while still in early stages, it shows promise for future applications in navigation and sensing technology.
Physicists have proposed a novel experiment to detect quantum behavior in large objects, challenging the traditional view that quantum effects are limited to tiny particles. The experiment involves observing the motion of an object, such as a ball on a pendulum, and flashing light at different times to determine if quantum behavior is occurring. If successful, this could provide evidence of quantum fuzziness on a larger scale and potentially be tested using the mirrors at the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the US.
Physicists from University College London, the University of Southampton, and the Bose Institute have proposed a novel approach to measure quantum behavior in larger objects, challenging the traditional view that quantum physics only applies at small scales. Their experiment involves observing the motion of an object on a pendulum and flashing light at different times to see if quantum behavior is occurring. If successful, this could extend the domain of quantum mechanics and test its validity for larger masses, potentially revolutionizing our understanding of the fundamental theory of nature.
