The broad research direction of our group is to develop superconducting circuits to couple to electron spin ensembles in the cQED architecture. These circuits are aimed at reaching quantum limit of detection sensitivity, high-fidelity control and manipulation for their potential use in quantum computing and quantum sensing. We design and fabricate these superconducting circuits entirely in-house. The measurements are performed in the microwave regime at few GHz, with magnetic field strength reaching up to Tesla, and at the base temperature of 10 mK. We are part of the National Quantum Mission in the vertical of quantum computing with superconducting circuits.
