Shantanav Chakraborty

Shantanav Chakraborty is an Assistant Professor at the International Institute of Information Technology, Hyderabad (IIIT Hyderabad), where he is affiliated with the Centre for Quantum Science and Technology (CQST) and the Centre for Security, Theory and Algorithmic Research (CSTAR). Previously, he was an FNRS postdoctoral fellow at the Centre for Quantum Information and Communication (QuIC) at Université libre de Bruxelles, working with Jérémie Roland. He received his PhD from the University of Lisbon in December 2017, where he was affiliated with the Physics of Information and Quantum Technologies Group under the supervision of Yasser Omar, and also spent time as a visiting researcher at QuSoft, CWI Amsterdam.

His educational background includes:

• B.Tech in Information Technology from West Bengal University of Technology (2007-2011)
• M.Tech in Computer Science and Engineering from IIT Jodhpur (2011-2013)
• PhD in Quantum Computing from the University of Lisbon (2017)

Dr. Chakraborty's primary research focuses on quantum computation and quantum algorithms. He has made significant contributions to the field of quantum walks, developing new algorithms and improving existing ones. His work extends to quantum linear algebra concepts such as block-encoding and quantum singular value transformation, which have applications in quantum machine learning and solving linear systems. Currently, he is investigating the algorithmic utility of near-term quantum computers with limited logical qubits and short circuit depths. His research bridges theoretical computer science with practical implementations for emerging quantum hardware.

An analysis of his recent publications reveals a strong focus on advancing quantum algorithm design for practical implementation. His work spans quantum walks, quantum linear algebra, and near-term quantum computing applications. A notable trend is his development of frameworks like block-encoding that unify different quantum input models. His research increasingly addresses the practical constraints of current quantum hardware while maintaining theoretical rigor, with recent papers focusing on intermediate-term quantum computers and their applications.

His notable scientific achievements include:

• Fujitsu Ltd. unrestricted research grant for 2024 and 2025
• SERB-DST Startup Research Grant (SRG) from the Government of India
• TCS award for "Best undergraduate thesis" for his work at ISI, Kolkata
• Publication in Physical Review Letters selected as an Editors' suggestion

Dr. Chakraborty actively supervises PhD and MS students, with several current advisees including Soumyabrata Hazra and Arnab Ghorui. He collaborates extensively with researchers globally, including institutions in Brussels, Amsterdam, and various Indian research centers. His current grants from Fujitsu and SERB-DST support his work on quantum algorithms for near-term devices. He has successfully secured funding to support PhD students working on quantum computation, algorithms, and complexity.

He is a core faculty member of the Centre for Quantum Science and Technology (CQST) at IIIT Hyderabad, which was recently launched to advance quantum research in India. His research group focuses on theoretical aspects of quantum computing with an emphasis on practical algorithm design for emerging quantum hardware. The team includes PhD students, MS students, and research associates working on various aspects of quantum algorithms and their applications.
