## Abstract

Recent observations for a pressurized kagome superconductor through transport, muon spin relaxation, nuclear magnetic resonance, and point contact spectroscopy demonstrate striking fluctuating superconductivity at a magic pressure. This discovery may hint at a new quantum dephasing mechanism, which can be discussed from the perspectives of correlation and topology. Three outstanding questions should be considered in decoding this mechanism: one is the intrinsic phase fragile nature of kagome superconductivity; second is the role of Coulomb interactions within different charge-ordered phases; third is the geometrical phase compatibility between superconductivity and different charge orders.
