Using discrete and continuous variable subsystems, hybrid approaches to quantum information could enable more quantum computational power for the same physical resources. Here, we propose a hybrid scheme that can be used to generate the necessary Gaussian and non-Gaussian operations for universal continuous variable quantum computing in trapped ions. This scheme utilizes two linear spin-motion interactions to generate a broad set of non-linear effective spin-motion interactions including one and two mode squeezing, beam splitter, and trisqueezing operations in trapped ion systems. We discuss possible experimental implementations using laser-based and laser-free approaches.

  1. Mid-circuit ground-state cooling and ancilla readout in the $\textit{omg}$ architecture

    quant-ph 2026-08 conditional novelty 6.0 of 10

    Two calcium ions in different electronic manifolds can sympathetically cool their shared motion to near the ground state and perform non-destructive readout of a metastable data qubit via a ground-state ancilla.

  2. Benchmarking trigonometric continuous-variable gate primitives with trapped ions

    quant-ph 2026-07 conditional novelty 6.0 of 10

    Cosine gates exp(-iθ cos(c x̂)) in one- and two-mode versions were implemented on trapped-ion motional modes and benchmarked against noise-inclusive simulations via Fock-space transition probabilities.
