Sumanta Khan 
Research Fellow

Dr. Sumanta Khan is leading the Grating-based lattice optical clock (G-BLOC) project within the Alkaline research group. He became a member of the research group in October, 2023. His research interest involves ultracold atoms, quantum information processing with trapped ions, coherent control spectroscopy. At present, he is dedicated to the development of a miniaturized optical lattice clock utilizing neutral Sr atoms.
