Research Description
Some of the best sensors in the world are derived from atomic vapor cells, floating atoms which are exquisitely sensitive to external fields. However, their sensitivity is reaching hard physical limits due to tradeoffs between number density, temperature and pressure these cells can reach. Justin Caram is trying to access atomic properties in dense solution phase, to circumvent these limits. He does this by using the ‘atom-like’ optical transitions in lanthanide complexes to protect coherent quantum states, which can be prepared, entangled and manipulated for the future of quantum sensing. This approach combines tools from solution phase spectroscopy, atomic physics, and chemical design in order to systematically develop and improve lanthanide complexes for sensing.
Research Impact
Disordered liquids make it hard to create or detect quantum states. Dr. Caram is aiming to design a chemical “cage” to protect embedded atomic transitions and open up the vast space of novel quantum sensors.
