Arun Kumar Pati (ଅରୁଣ କୁମାର ପତି) is an Indian physicist notable for his research in quantum information and computation, the theory of geometric phases and its applications, and the foundations of quantum mechanics. He is considered a pioneer in the field of quantum information and quantum computation in India.
Originally from the state of Orissa in India, 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 Professor at Zhejiang University, Hangzhou, China during the period 2013-2015. 
Along with Samuel L. Braunstein, he proved the quantum no-deleting theorem. His other important collaborative work with Braunstein includes the quantum no-hiding theorem. This has applications that include quantum teleportation, quantum state randomization, thermalization and the black hole information loss paradox. The no-hiding theorem has been experimentally tested and this is a clear demonstration of the conservation of quantum information. He also discovered the remote state preparation protocol in quantum information theory, which has been experimentally tested by several groups. He along with other scientists introduced the concept of geometric phase for mixed states. This has been experimentally measured by several groups around the world.
Pati is the recipient of the India Physics Association Award for Young Physicist of the Year (2000) and the Indian Physical Society Awards for Young Scientists (1996). He is also recipient of Samanta Chandra Sekhar Award for the year 2009 from Orissa Bigyan Academy, Bhubaneswar, Orissa. He is an elected Fellow of the Indian Academy of Science, Bangalore. He also has been elected as the Fellow of "The National Academy of Sciences, India in 2013. His research has been featured in news items in Nature and Science.
