Abstract
Semiconductor qubits are compact, highly coherent and can be manufactured in industrial facilities. Single-and two-qubit gates reach fidelities well over 99%, and two-dimensional qubit arrays of increasing sizes are being realized. In the last few years, a new opportunity has been explored with great success, based on shuttling electrons around the chip while preserving spin coherence, allowing us to create reconfigurable interactions. In addition, we have shown that the act of shuttling in itself can be harnessed to perform tunable and high-fidelity single- and two-qubit operations. This is leading us to rethink how to construct large-scale, fault-tolerant quantum processors, taking advantage of mobile qubits.
Bio
Lieven Vandersypen received a MSc in Mechanical Engineering from KU Leuven and a MSc and PhD in Electrical Engineering from Stanford University (2001). He then moved to TU Delft, the Netherlands, first as a postdoc and since 2006 as Antoni van Leeuwenhoek professor. Prof. Vandersypen received Starting, Synergy and Advanced grants of the European Research Council, is a fellow of the American Physical Society (APS), a member of the Royal Netherlands Academy of Arts and Sciences (KNAW) and the Royal Holland Society of Sciences and Humanities (KHMW), and was a member of the Young Academy of the KNAW. He was selected as an Outstanding Referee of the APS, received the IUPAP Young Scientist Prize for Semiconductor Physics, the Nicholas Kurti European Science Prize, and the Spinoza Prize, the highest scientific award in the Netherlands.
