In the quantum HO-based setup, a higher-energy HO acts as the charger and a lower-energy one as the battery. When the two are ...

Synchronization phenomena continue to inform and surprise. In classical and quantum physics, the harmonic oscillator is a paradigmatic model both because it describes periodic behaviour found in a ...

The research team applied the Page and Wootters mechanism, a theory proposed in 1983, to two entangled quantum states : ・A vibrating harmonic oscillator ・A set of tiny magnets acting as a ...
