Separately, platforms with native continuous-variable (CV, oscillator) systems have emerged as promising alternatives. In this talk, I will introduce a new hybrid CV-DV quantum computing paradigm that combines the strengths of both architectures, and highlight novel quantum algorithms and applications enabled by them. I will start with the qubit land, and present novel state preparation and dynamics simulation algorithms with application to quantum chemistry and beyond. This includes the first benchmarking study of a novel quantum embedding algorithm on real quantum hardware. I will then switch to hybrid CV-DV, and begin with a pedagogical overview of CV-DV processors, their instruction set architectures, and universal programmability. I will then present a variety of new hybrid CV-DV algorithms and applications, including the extension of quantum signal processing concepts to CV-DV systems and strategies to simulate systems of interacting spins, fermions, and bosons. These developments together open new frontiers for quantum simulation and computation for challenging problems across science and engineering. I will conclude with open questions and future opportunities.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u0026nbsp;\u003C\/strong\u003EDr. Yuan Liu is an Assistant Professor and Quantum Computing \u0026amp; Information Science Faculty Fellow at North Carolina State University, with joint appointments in Electrical \u0026amp; Computer Engineering, Computer Science, and Physics.
