Time as an illusion created by entanglement in Physical Review A featured in WIRED
ISC researchers Alessandro Coppo and Paola Verrucchi, in collaboration with Prof. A. Cuccoli from the University of Florence, have published an intriguing study in Physical Review A. The work has garnered attention from prominent publications such as New Scientist and Wired.
They consider a simple and physically relevant example where the time evolution of a system can be determined by the entanglement with its clock. In this framework, they show that the standard notion of time emerges when conditions related to macroscopicity are met by the clock alone, or by both the clock and the evolving system. This emergung behavior encompasses the classical dynamics, as well as the phase-space and the trajectories on it.
The work follows the route outlined in a previous interesting article published in Nature Communications, briefly presented here.
