TL;DR
This paper proposes an experimental approach using matter-wave interferometry to test the continuous spontaneous localization (CSL) theory for large clusters, potentially challenging existing CSL constraints.
Contribution
It introduces a novel all-optical interferometry method to test CSL in high-mass particles, expanding the experimental mass range for quantum superposition tests.
Findings
Feasibility of testing CSL with clusters over 1,000,000 amu
Assessment of environmental decoherence effects
Potential to challenge existing CSL bounds
Abstract
We propose to test the theory of continuous spontaneous localization (CSL) in an all-optical time-domain Talbot-Lau interferometer for clusters with masses exceeding 1000000 amu. By assessing the relevant environmental decoherence mechanisms, as well as the growing size of the particles relative to the grating fringes, we argue that it will be feasible to test the quantum superposition principle in a mass range excluded by recent estimates of the CSL effect.
