Contribution

It provides the first detailed calculation of decoherence due to vacuum fluctuations and suggests an experimental approach to observe this effect.

Findings

Decoherence effect is quantifiable and significant under certain conditions.

Proposed experimental setup could detect vacuum fluctuation-induced decoherence.

Insights gained may advance understanding of vacuum fluctuations and decoherence mechanisms.

Abstract

The interaction of a particle with vacuum fluctuations--which theoretically exist even in the complete absence of matter--can lead to observable irreversible decoherence if it were possible to switch on and off the particle charge suddenly. We compute the leading order decoherence effect for such a scenario and propose an experimental setup for its detection. Such a measurement might provide further insights into the nature of vacuum fluctuations and a novel precision test for the decoherence theory.
