Aditi Sen De started her research in the field of quantum information theory during her postgraduate studies in Kolkata, and went on obtain her doctorate in 2004 at the University of Gdańsk. The field of quantum information and computation was still in its early days, and Gdańsk, Poland was one of the main research centres in the world, where important work on the theory of quantum entanglement was being done. In collaboration with her supervisor Marek Żukowski, and other eminent physicists such as Ryszard Horodecki, Paweł Horodecki, Michał Horodecki and her husband, Ujjwal Sen, she worked on some fundamental problems on entanglement theory, quantum cryptography and quantum communication. After her stint in Gdańsk, she joined the group of Maciej Lewenstein in Hannover, Germany and later in ICFO - The Institute of Photonic Sciences in Castelldefels near Barcelona, Spain, where she spetd a considerable period of her early research career. During this period, she consolidated her research on quantum information, while contributing heavily to new research directions that were opening in the interface of quantum information and many-body quantum physics. In particular, her research focused on the study of quantum phase transitions using entanglement as a key figure of merit. After a brief stint as a faculty member in Jawaharlal Nehru University, she moved to Harish-Chandra Research Institute in Allahabad, where along with physicists Ujjwal Sen and Arun Kumar Pati, she started the Quantum Information and Computation group in 2009, under the Physics Division at the institute. Over the last few years, several young researchers have completed their doctoral as well as postdoctoral research at the group, resulting in more than 50 publications in well-known journals in physics. The group has also hosted several conferences and workshops, with participants and speakers from all around the world.
