Abstract

Current methods for measuring magnetic flux are based on performing many measurements over a large ensemble of electrons. We propose a novel method based on wavefunction "revival" for measuring the flux modulo hc/2e using only a single electron. A preliminary analysis of the feasibility of the experiment is provided.

Keywords

magnetic flux single electron wavefunction revival quantum measurement aharonov-bohm effect flux quantization
