Overview of Academic Research
Dr. Li Lu is an experimentalist working on low temperature physics. He has been focusing on to explore the Fu-Kane scheme of topological quantum computation for more than two decades. In 2011, his team observed the first zero-bias conductance peak in a hybrid device composed of s-wave superconductor and topological insulator (TI). In the same year, they fabricated the first TI-based dc-SQUID. And in 2015, they fabricated the first TI-based rf-SQUID. From 2016 to 2018, they discovered topologically-protected gap closing in TI-based Josephson junctions. In 2019, his team successfully constructed TI-based Josephson trijunctions - the building block for topological quantum computing circuit proposed by Fu and Kane in 2008, and verified the Majorana phase diagram of the trijunctions. In 2022, the team further demonstrated the manipulation of trijunction’s Majorana phase diagram via anomalous Josephson effect. In 2024, they realized controllable creation of Majorana corner states in a Josephson corner junctions constructed on TI. And, they also realized fast parity readout of an artificial Kitaev chain by using a superconducting transmon.
Dr. Li Lu’s current research interest lies in the manipulation of Majorana zero modes in TI-based Josephson devices containing multiple trijunctions.
