He was a professor of quantum information at the Harish Chandra Research Institute, Allahabad, India from January 2011 to December 2023.

He is a Professor and Head of the Center for Quantum Science and Technology (CQST), at IIIT, Hyderabad from January 2023-December 2024.

Currently, he is a Professor at Center for Quantum Engineering Research and Education (CQuERE), TCG CREST, Kolkata.

[5] Pati also discovered the remote state preparation (RSP) protocol in quantum information theory.

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.

Pati along with Artur Ekert, Vlatko Vedral and other scientists have introduced the concept of geometric phase for mixed states.

He is also recipient of Samanta Chandra Sekhar Award for the year 2009 from Orissa Bigyan Academy, Bhubaneswar, Odisha.
