Amarendra Kumar Sarma

Dr. Amarendra Kumar Sarma is a full Professor in the Department of Physics at the Indian Institute of Technology Guwahati (IIT Guwahati), where he has been faculty since 2007 and Professor since 2018. He leads the Theoretical Quantum Optics and Quantum Technology Group, focusing on frontier areas of quantum science including quantum optomechanics, entanglement, and nonlinear photonics.

His research explores quantum technology through multiple interconnected domains:

• Quantum Hybrid Systems: Integrating superconducting qubits with optomechanical elements for quantum transduction and sensing
• Nonlinear Dynamics: Soliton physics, PT-symmetric optics, and ultrafast switching in waveguides
• Quantum Control: Entanglement generation, mechanical squeezing, and quantum synchronization techniques
• Quantum Metrology: Overcoming standard quantum limits for force sensing using electro-optomechanical approaches

Analysis of his 15 most recent publications (2018-2025) reveals strong emphasis on hybrid quantum systems (60% of works), with particular focus on quantum-classical interfaces for sensing applications. PT-symmetry and nonlinear dynamics constitute 30% of output, while quantum information fundamentals comprise 10%. Machine learning integration emerges as a new frontier in quantum control methodologies.

He actively mentors researchers including 7 current PhD students and 12 former advisees. Notable grants include:

• STARS-2 project: 'Exploring Hybrid Circuit QED Systems for Quantum Technology' (2024-2027)
• SERB MATRICS: 'Soliton Dynamics in PT-Symmetric Models' (2020-2023)
• DST Fast-track: 'Parity-time Symmetry in Nonlinear Optics' (2014-2017)

The Quantum Optics and Quantum Technology Group develops theoretical frameworks for experimental quantum implementations, maintaining collaborations with international institutions in quantum materials and device physics.
