I am a postdoc in the Girvin and Puri groups at Yale University studying possible physical implementations of QRAM. I received my PhD from Northwestern University in Jens Koch’s group where I studied noise protected superconducting circuits (like the current mirror) as well as novel techniques for coupling and controlling fluxonium qubits.
