Currently researchers in the field of personalized recommendations bear little consideration on users' interest differences in resource attributes although re- source attribute is usually one of the most important factors in determining user pref- erences. …

Robust Mølmer-Sørensen Gate Against Symmetric and Asymmetric Errors

2025 · arXiv (Cornell University)

To achieve the entangling gate fidelity above the quantum error correction threshold, it is critical to suppress errors due to experimental imperfection. We consider the Mølmer-Sørensen gates in trapped-ion systems, and develop a general approach …
