Research Interests

Being the fundamental law of nature, quantum mechanics determines the performance of all physical processes. These include typical information processing tasks such as computation, communication, sensing, and simulation. My interest lies in the limits that quantum mechanics sets on information processing, and the unique advantages that it enables in such tasks. I have been particularly interested in quantifying the resources that are necessary for quantum enhancements, as well as designing protocols that exhibit tangible quantum advantages in realistic scenarios. I am also interested in studying noisy processes where quantum principles may play a crucial role, such as energy transport in light harvesting complexes. The motivation is two-fold : to study the robustness of quantum correlations in noisy processes, and exploit this understanding in designing systems that show quantum advantages in realistic scenarios. The quantum information science group I lead has similar motivations and interests.

Academic Bio

I am a Professor of Theoretical Physics and lead the quantum information science group. I held an EPSRC Early Career Fellowship during 2014-19 and joined Warwick as an Assistant Professor in 2015.

I obtained a B. Tech. in Electrical Engineering (with a minor in Physics) from the Indian Institute of Technology, Kanpur in 2003. I received my PhD in Physics in 2008 from the University of New Mexico, working with Carl Caves, after which I held a postdoctoral position at Imperial Collge London. I next held a postdoctoral position at the University of Oxford, where I led my own research group from 2014.
