A train of voltage pulses can be used for time‐domain spectroscopy of quantum‐coherent structures, as shown by Christian Flindt and co‐workers in article number 1900014. When single‐electron excitations are periodically injected into a mesoscopic circuit, the distribution of waiting times between the outgoing charges contains detailed information about the characteristic timescales of the device. The development of single‐particle emitters and detectors suggests that the proposal may soon be within reach.
