Research interests
​
I have worked on a broad range of topics. In quantum information, I have proposals for the major elements required for quantum internet i.e. quantum memory, single-photon source, photonic switch and transistor, and quantum gates required for quantum repeater operation, quantum error corrections and quantum computation at the nodes. These proposals were implemented in atoms, photons, superconducting circuits, ions, cavity arrays, and Cu2O crystals. I also have proposals for making large energy, spin, and mechanical superposition with applications in the test of collapse models as well as improving the precision of atomic clocks. In quantum matter, I have worked on solitons and super-solid materials. At the moment, I am working on the quantum simulation of topological insulators.
