Hanhee Paik received a Ph.D. in Physics from University of Maryland, College Park. She was a post-doctoral fellow at LPS and moved to Yale University to work with Profs. Robert Schoelkopf, Michel Devoret and Steve Girvin. Through her research career, she has been focusing on understanding and improving coherence mechanisms of superconducting qubits, and developing novel superconducting multi-qubit architectures.
Dr. Paik pioneered the new design of a superconducting qubit where she used, for the first time, a single Josephson junction with macroscopic-scale shunt capacitor pads. The new qubit exhibited nearly two orders of magnitude longer coherence times (time a quantum computer can operate) than the prior state-of-art. Her research on the quantum processor design has greatly impacted the quantum computing community by proving the true coherent nature of superconducting qubits, and helped the community understand coherence mechanisms in qubits. The new qubit design also helped the industry to push the boundary of superconducting qubit performance, and played an important role in advancing the technologies for quantum measurement and feedback, and superconducting quantum optics with the improved coherence.
Today’s IBM Q commercial 20 qubit systems’ coherence times benefit from Dr. Paik’s work, and average an industry-best 100 microseconds. She is currently working on developing the next generation quantum computing processors. She played a pivotal role developing the 16-qubit IBM Q Experience device.
