08/01/2024 | Dr. Liu’s paper Quantum state tracking and control of a single molecular ion in a thermal environment is published in Science! This work was carried out during Dr. Liu’s postdoc at the Ion Storage Group in NIST, Boulder. Thank you to everyone who contributed to this project!
In this work we prevented a single molecule (CaH+) from thermalizing to the surrounding room temperature environment, by frequent measurement and active correction of the molecule’s quantum state. The improvement in the ability to control molecular quantum states against environmental perturbations could benefit the applications of molecules in quantum information science. The Quantum logic based detection technique demonstrated here may be applied to studying other processes (e.g., inelastic collisions, strong pulse excitations) on a single molecule, single state level, in a wide range of molecule species.
