Summary

Story summary

Researchers from ETH Zürich and Spain’s Institute of Photonic Sciences are enhancing quantum mechanics using nanoparticles.
They focus on increasing mass and coherence length to observe quantum phenomena in larger objects.
Lead researcher Massimiliano Rossi addresses the challenge of limiting decoherence, which disrupts quantum information.
The team measured and suppressed decoherence sources, achieving a coherence length of 73 pm, larger than the nanoparticle's 100 nm size.
Future studies may explore hybrid traps with light and electric fields to improve coherence length.
