How to Measure Magnetic Flux with a Single Position Measurement?

TL;DR

This paper introduces a novel single-electron method for measuring magnetic flux using wavefunction revival, potentially simplifying flux measurement by reducing the need for multiple measurements over many electrons.

Contribution

It proposes a new wavefunction revival-based technique for magnetic flux measurement that requires only a single electron, contrasting with traditional ensemble-based methods.

Findings

Feasibility of single-electron flux measurement analyzed

Method measures flux modulo hc/2e

Preliminary experimental considerations discussed

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.
