Prize Recipient

Rishabh Sahu
Institute of Science and Technology Austria

"For realizing a high-cooperativity electro-optic interconnect demonstrating ultra-low noise conversion and the first observation of microwave-optical entanglement, thus laying the experimental foundations for the new field of cavity quantum electro-optics."

Rishabh completed his bachelor’s and master’s degree in Physics at the Indian Institute of Technology, Kanpur. His research mainly involved studying orbital angular momentum (OAM) of light, in particular, developing an "angular lens", that is analogous to an optical lens, which sorts light with different OAMs just like a normal lens sorts different planar waves. His master’s thesis involved developing parallel C++ code which solves Maxwell’s equations using the Finite Difference Time Domain (FDTD) method. Rishabh started graduate school at Institute of Science and Technology Austria (ISTA) in fall of 2018 and joined the Fink group in 2019. At ISTA, he worked on an electrooptic platform to bridge the gap between microwave and optical frequencies which is required to connect future microwave-based quantum computers such as superconducting qubits to a quantum network run at optical telecom frequency. He demonstrated high efficiency quantum transduction and deterministic entanglement between these frequencies and also direct dynamical backaction between the microwave and optical modes. Rishabh is now a postdoc at Fink group since June 2023 where he conducts further experiments with microwave-optical transducers and superconducting qubits.
