A new study demonstrates a near-complete control of quantum states in chiral molecules, achieving up to 96% purity. This advancement in molecular physics could profoundly impact our understanding of life’s molecular foundations and the universe’s asymmetries. Credit: FHI
This breakthrough involves using tailored microwave fields and ultraviolet radiation, allowing for a 96% purity in quantum state control, which has significant implications for understanding biological homochirality and fundamental universe symmetries. The ability to control these molecules and their quantum states has profound implications, from spatial separation of enantiomers in the gas phase to testing hypotheses about the origins of life’s homochirality – the preference for one mirror image over the other in biological systems.Until now, the scientific community believed that perfect control over these molecules’ quantum states was theoretically possible but practically unattainable.
In the experiment, a beam of molecules, with their rotational motions mostly suppressed , traverses three interaction regions where it is exposed to resonant UV and microwave radiation.
