An experiment to test the discreteness of time

Understand

Time at the Planck scale ($\sim 10^{-44}\,\mathrm{s}$) is an unexplored physical regime.

• It is widely believed that probing Planck time will remain for long an impossible task.
• Yet, we propose an experiment to test the discreteness of time at the Planck scale and estimate that it is not far removed from current technological capabilities.
