We present a method to estimate the time scale of quantum jumps from the time correlation of photon pairs generated from a cascade decay in an atomic system, and realize it experimentally in a cold cloud of 87Rb. Taking into account the photodetector response, we find an upper bound for the duration of a quantum jump of 21+/-11 ps.

We estimate the time scale of quantum jumps from the time correlation of photon pairs generated from a cascade decay in a cold cloud of 87Rb. We find an upper bound of $21\pm 11$ ps. © 2019 The Author(s)
