Mass-dependent reduction in interference visibility was observed, dropping from near unity to below 0.2.
Coherence times exceeded one second for particles lighter than 10^(-16) kg, indicating potential for longer quantum states.
Environmental thermal radiation was confirmed as the dominant decoherence source for heavier nanoparticles at room temperature.
The findings highlight the need for cryogenic and ultra-high vacuum conditions to successfully observe gravitational quantum phases.
