Urbasi Sinha is an Indian physicist and professor at the Raman Research Institute. Her research considers quantum information science and quantum photonics. She was named in the Asian Scientist 100 list in 2018, appointed an Emmy Noether Fellow in 2020 and awarded the Chandrasekarendra Saraswathi National Eminence Award in 2023. She was awarded the Vigyan Yuva Shanti Swarup Bhatnagar Award in the Physics category in 2024. ^[1]

Early life and education

Sinha was born in London and completed her undergraduate from Jadavpur university graduate and doctoral degrees at the University of Cambridge. Her research considered superconducting devices. ^{[2] [3]} Her doctorate involved explorations of the Josephson effect. ^{[4] [5]} She moved to the Institute for Quantum Computing for her postdoctoral research, ^[6] where she became interested in quantum computing and optics. Here she developed a triple-slit variation to the double-slit experiment; testing the Born rule. ^{[7] [8]} The Born rule predicts the probability that a measurement made in a quantum system will give a particular result.

Research and career

She served as an Associate Professor at the Raman Research Institute from 2012 to 2019, and was appointed as a Professor there in 2020. ^[9] At Raman Research Institute, she leads the Quantum Information and Computing (QuIC) Laboratory, where she began working on quantum photonics and the development of a quantum internet. Alongside technological applications, Sinha is interested in testing fundamental quantum phenomena, including Leggett–Garg inequality.

In 2017, Sinha was appointed a Homi Bhabha Fellow at the Cavendish Laboratory. ^[10] In 2020, Sinha became an Emmy Noether Fellow at the Perimeter Institute for Theoretical Physics. ^[2] Her research group demonstrated a quantum communication channel between fixed and moving platforms in 2023, the same year she was awarded a Canada Excellence Research Chair in Photonic Quantum Science and Technologies at the University of Calgary. ^{[11] [12] [13]} Sinha is also involved with designing the National Quantum Mission India. ^[14]
