Research interest: Cold atom quantum technology

The beauty of cold atom based quantum technologies is that, one can design versatile quantum systems and fully control their properties by simple and clever approaches, just because of the inherent quantum nature of atoms and photons. In one approach we cool atoms to million times colder than room temperature using precisely frequency tuned lasers. In a second approach we trap these cold atoms in optical potentials even to the single particle level. With these abilities, we can design textbook like quantum systems with few individually addressable atoms. The real world problems demand to build large quantum systems beyond textbook examples. The biggest challenge in achieving this goal is to know how to control the environment induced decoherence. In our research group we aim to address these open problems in a step by step manner. These technological and conceptual developments will lead us to build large scale quantum information processing network, quantum computation protocols for solving industry and society relevant problems, quantum sensing devices and quantum metrology modules for precision instrumentations and measurements.

About Bodhaditya Santra:

Bodhaditya Santra is an assistant professor of Physics at Indian Institute of Technology Delhi. His research group is building experiments to explore cold atom quantum technologies to address various problems in society and industry.

He studied physics at the University of Burdwan, India and at the Indian Institute of Technology Kharagpur, India. In 2008, Bodhaditya joined the group of Dr. Lorenz Willmann/ Prof. Klaus Jungmann at the University of Groningen, Netherlands to work on laser spectroscopy of short lived radium atoms. In 2013 he received his PhD degree for the thesis work on "Precision spectroscopy of neutral radium: towards searches for permanent electric dipole moments".

From 2013 to 2016 he worked as a postdoctoral research fellow in the group of Prof. Herwig Ott at the University of Kaiserslautern, Germany to study the microscopic dynamics of ultracold quantum gases in optical lattices. He used a scanning electron microscope to achieve high resolution imaging and single site addressability of Bose condensed rubidium atoms in optical lattices. In 2015, he received a grant from the University of Kaiserslautern to study the coherence dynamics of Bose-Einstein condensates in optical lattices. From 2016 to 2018 he worked on ytterbium quantum gases in optical lattices in the group of Prof. Klaus Sengstock at the University of Hamburg, Germany. In this project he investigated many-body physics in SU(N) symmetric fermionic quantum systems using ytterbium optical lattice clock. From 2018 to 2019 he worked on quantum mixtures, dipolar molecules under a microscope and tunable quantum matter in optical lattices in Prof. Hanns-Christoph Nägerl’s group at the University of Innsbruck.
