Sergey Hazanov is a PhD candidate in the Faculty of Physics at the Weizmann Institute of Science, where his research focuses on superconducting qubits for quantum computing. His work aims to make these qubits more robust, a key step toward building reliable quantum computers. Supported by the Chateaubriand Fellowship, Sergey spent eight months in the Quantum Circuits Group at ENS Lyon, under the supervision of Prof. Benjamin Huard, in collaboration with Alice & Bob, a French quantum-computing startup. There he helped develop a new generation of a promising qubit design that is inherently more resilient to noise, contributing to its circuit design, simulations, and first measurements. This experience greatly advanced his doctoral research and strengthened the scientific ties between his lab at the Weizmann Institute and the French quantum-computing community.
