RF Side-Channel Attack on Trapped-Ion Quantum Processors

Researchers demonstrate a passive, non-invasive RF side-channel attack on a trapped-ion QPU using off-the-shelf hardware, extracting gate timing and ion addressing data from AOM electromagnetic leakage without modifying the target system.

Active Cancellation of Power-Line-Induced Motional-Mode Frequency Noise in Trapped-Ion Quantum Computing

Seoul National University demonstrates first active cancellation of periodic motional-mode noise in a trapped-ion system, extending radial mode coherence from ~10ms to ~35ms via phasor-optimized feedforward injection into a PI controller's RF set-point.

Tangent Space Decomposition for Characterizing Coherent and Non-Markovian Quantum Gate Errors

A geometry-based tangent space decomposition on CPTP map manifolds separates coherent, Markovian, and non-Markovian error contributions from a single tomographic snapshot, validated experimentally on a trapped ⁴⁰Ca⁺ ion qubit.
