Researchers at the University of Rochester have developed a method to extract the spectral density for molecules in solvent using resonance Raman experiments, allowing for a better understanding of quantum decoherence. By mapping decoherence pathways, scientists can now connect molecular structure with quantum decoherence, opening the door to designing molecules with specific quantum coherence properties. The team demonstrated how electronic superpositions in thymine, a DNA building block, unravel in just 30 femtoseconds following UV light absorption. They also found that chemical modifications to thymine can significantly alter the decoherence rate.

Researchers at the University of Chicago have successfully observed many-body chemical reactions in a quantum degenerate gas, marking a significant step towards understanding and controlling chemical reactions at the quantum level. Using Bose-condensed cesium atoms, the team observed coherent, collective reactions between atoms and molecules, demonstrating macroscopic quantum coherence and Bosonic enhancement. These "super reactions" resemble superconductivity and laser functioning, but with molecules instead of electrons or photons. The findings provide insights into the dynamics of quantum many-body chemical reactions and offer potential applications in precision metrology, quantum information, and quantum control of chemical reactions.
