Raytheon BBN Technologies

Staff Scientist

Hanhee Paik is a Scientist in the Quantum Information Processing group at Raytheon BBN technologies, received Ph.D. in Physics from the University of Maryland under the supervision of Prof. Fred Well-stood and Chris Lobb with a thesis on the study of decoherence in dcSQUID phase qubits. She was a post-doctoral researcher at LPS and Yale University. During her post-doc at LPS, she investigated the cryogenic microwave loss mechanisms in amorphous silicon nitride, a material used in fabricating highly-integrated superconducting quantum circuits. At LPS, she synthesized a new amorphous silicon nitride film with 50 times lower cryogenic microwave loss than other commonly-used amorphous dielectrics and opened possibilities to build high-Q integrated superconducting quantum processors. While at Yale, she invented a three-dimensional (3D) superconducting circuit QED architecture with her advisor Prof. Robert Schoelkopf, which made a big breakthrough in improving coherence of superconducting quantum circuits by two orders of magnitude. She also worked on developing a circuit design tool for superconducting qubits and a new entangling gate scheme that achieved 99% fidelity in entangling two-qubit operation in the 3D architecture, the highest fidelity demonstrated in superconducting qubits up to date.
