  "abstract": "Non-Gaussian gates remain a key bottleneck for universal continuous-variable (CV) quantum computation because the nonlinearities they require are difficult to engineer. To address this challenge, we develop an efficient qubit-oscillator Rabi synthesis scheme for polynomial phase gates, with a total interaction time that scales polylogarithmically with the inverse target error \\(\\varepsilon\\). Specifically, for a class of readily preparable initial states, we show that a degree-\\(R\\) phase gate can be approximated by an analytically constructed Rabi sequence with total time \\(O(\\log^{(R-1)/2+o(1)}(1/\\varepsilon))\\). This construction requires no numerical optimization and therefore extends naturally to arbitrarily large multimode systems. We further establish a total-time lower bound of \\(Ω(\\log^{(R-1)/2}(1/\\varepsilon))\\), showing that the synthesis is near optimal. As applications, we use this scheme to simulate representative CV quantum dynamics and implement a CV quantum algorithm for solving linear partial differential equations. These results establish qubit-oscillator Rabi control as an efficient, analytically compilable, and near-optimal primitive for CV quantum information processing.",
