Quantum coherence is one of the most important topics in fundamental physics. In mesoscopic systems, decoherence has often been studied using Aharonov-Bohm (AB) interferometers, and in such a coherent transport, it is well known that probes of a sample play an essential role and transport property has been successfully
described by the Landauer-BˇŻuttiker (LB) formalism.1) Here we present evidence that the quantum coherence itself is also a?ected by the probe con?guration.
