A unique type of electron source has emerged which permits to inject particles in a controllable manner, one at a time, into an electronic circuit. Such single-electron sources make it possible to address experimentally one of the most fundamental quantum properties of an electron, its coherence length. We propose a methodology to measure the single-particle coherence length from the decay of the Aharonov-Bohm oscillations as a function of the imbalance of a Mach-Zehnder interferometer.
