Arun Kumar Pati

Arun Kumar Pati

Harish Chandra Research Institute


Arun Kumar Pati is an Indian physicist notable for his research in quantum information and computation, the theory of geometric phases and its applications, as well as quantum mechanics. He is considered an important physicist in the field of quantum information and quantum computation in India, perhaps the first. Pati obtained his PhD from the University of Bombay, Mumbai. In 1989, he took up a position as a theoretical physicist in the Theoretical Physics Division, BARC, Mumbai, India. From 1998-2000, he was a visiting scientist and an EPSRC fellow at the University of Wales, Bangor, UK. He was a visiting scientist at the Institute of Physics, Bhubaneswar, India from 2001-2010. Currently, he is a Professor of Quantum Information at the Harish Chandra Research Institute, Allahabad, India since 2011. He is honored with K. P. Chair Professorship at Zhejiang University, Hangzhou, China during the period 2013-2015.

Research Interest

Current research topics include all aspects of quantum information, in particular quantum entanglement, quantum correlations, quantum speed limit, weak measurements, stronger uncertainty relations, monogmy and polygamy of various correlation measures, quantum coherence, entanglement in non-Hermitian quantum theory and their consequences. I have been also collaborating with experimentalists to test some of our theoretical predictions.
