Superradiant atoms can help us measure time more precisely than ever. In a recent study, researchers from the University of Copenhagen present a new method for measuring the time interval, the second, mitigating some of the limitations that today’s most advanced atomic clocks encounter. The result could have broad implications in areas such as space

A team of researchers has proposed an approach to quantify entanglement using the standard entanglement witness procedure under three common experimental scenarios. Their work is published in Physical Review Letters.Quantum Physics NewsRead More

Though “coupled oscillations” may not sound familiar, they are everywhere in nature. The term “coupled harmonic oscillators” describes interacting systems of masses and springs, but their utility in science and engineering does not end there. They describe mechanical systems like bridges, the bonds between atoms, and even gravitational tidal effects between the Earth and the
