Quantum Thermo-Electric Circuits
Quantum thermal analogues of electric circuits, heat-current driven architectures, thermal circuit components and steady-state quantum device engineering.
About
Research at the interface of quantum information, thermodynamics, dynamics and quantum hardware.
My research lies in quantum information science, with emphasis on the thermodynamic and statistical analysis of information processing, quantum resource theories, Markovian and non-Markovian dynamics, quantum device engineering, and cavity quantum electrodynamics.
I joined IIIT Hyderabad in December 2019. My research program combines fundamental quantum information theory with experimentally motivated quantum hardware, cavity-QED systems, quantum thermo-electronics and quantum opto-mechanics.
