Sumit Goswami

Research Scientist, CQuERE

Dr. Goswami studied for his BS-MS in Physics at IISER Kolkata. He earned his Ph.D. in theoretical quantum optics research from the University of Calgary, Canada, focusing on quantum networks. Later Dr. Goswami completed his postdoctoral research at Academia Sinica, Taiwan. Being a quantum optics theorist his primary research focus is on quantum technologies, specifically on satellite quantum networks and quantum interconnects.

One of his most interesting works include a proposal for global scale quantum networks without quantum memories or repeaters – instead it proposes a satellite-chain architecture that uses only reflection. His work on quantum interconnects is based on cavity QED systems -connecting atomic qubits through an optical cavity. He has been awarded several fellowships during his career like NTSE and KVPY scholarships in India and Dean’s international doctoral fellowship, Izaak Walton Killam Doctoral fellowship, Eye’s High fellowship etc in Canada.

Dr. Goswami joined CQuERE, TCG CREST in April of 2026 and has been working as a research scientist in Theoretical quantum optics research with a focus on quantum technology applications, specifically on satellite quantum networks and quantum interconnects.
