science college aska during 1981 1985 he completed his master s degree in physics from berhampur university odisha in 1987 subsequently in 1988 he joined the training school program at barc mumbai india career edit originally from the state of odisha 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 since 1989 he has been working on quantum theory quantum computing and quantum information from 1998 to 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 to 2010 he was a professor of quantum information at the harish chandra research institute allahabad india from january 2011 to december 2023 he was a professor and head of the center for quantum science and technology cqst at iiit hyderabad he was also a professor at center for quantum engineering research and education cquere tcg crest kolkata he is founding director of quantum ecosystem and technology council of india qetci hyderabad he is honored with k p chair professorship at zhejiang university hangzhou china during the period 2013 2015 1 2 he is an adjunct professor at iiser mohali work edit along with samuel l braunstein he proved the quantum no deleting theorem similar to the no cloning theorem the no deleting theorem is a fundamental consequence of the linearity of quantum mechanics 3 this proves that given two copies of an unknown quantum state we cannot delete one copy the no cloning and the no deleting theorems suggest that we can neither create nor destroy quantum information his other important collaborative work with braunstein includes the quantum no hiding theorem this states that if quantum information is lost from one subsystem then it remains in the rest of the universe and cannot be hidden in the quantum correlation between the original system and the environment this has applications that include quantum teleportation quantum state randomization thermalization and the black hole information loss paradox 4 the no hiding theorem has been experimentally tested and this is a clear demonstration of the conservation of quantum information 5 pati also discovered the remote state preparation rsp protocol in quantum information theory this is an important quantum communication scheme similar to quantum teleportation in rsp protocol alice can prepare a known qubit chosen from special ensemble at bob s location using a maximally entangled state and one bit of classical communication this has been experimentally tested by several groups pati along with artur ekert vlatko vedral and other scientists have introduced the concept of geometric phase for mixed states this has been experimentally measured by several groups around the world in another fundamental work pati along with l maccone have discovered stronger uncertainty relations that go beyond the heisenberg uncertainty relation these new relations capture the notion of incompatible observables and show that quantum world is more uncertain than what heisenberg robertson s uncertainty relation has explicated us 6 honors edit 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 odisha 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 7 he received j c bose fellowship from the department of science and technology dst government of india in 2019 he received distinguished alumni award from berhampur university odisha on its 55th foundation day in 2021 his important research work have been featured in news items in nature nature asia and science 8 arun k pati has been in the world rank list of top 2 scientists recently published by the stanford university he is also among top 1
