Expanding the Toolbox for Superconducting Circuits
Superconducting circuits have become a leading platform in the pursuit of fault-tolerant quantum computing and many-body quantum simulations. In this talk, I will present novel approaches to circumvent known problems in superconducting architectures, with a focus on the hardware design and the choreography of qubit-qubit interactions. Specifically, the talk will focus on fluxonium as the building block and Floquet mapping as the framework for tailoring multi-qubit interactions in future platforms. Based on these concepts, I will discuss ongoing efforts on noise-protected platforms such as biased-noise fluxonium and grid-states qubit.
Long B. Nguyen received his Ph.D. in 2020 from the University of Maryland, where he explored an alternative superconducting circuit platform for quantum computing and quantum information processing. Afterwards, he decided to stay in the same field and joined the group of Prof. Irfan Siddiqi as a postdoctoral scholar. The overarching theme of his current projects is to transform the way quantum information is encoded and manipulated in superconducting systems. When not doing research or spending time with his family, Long enjoys sharing coffee and boba tea with other lab members.
