Closed-loop control for two-qubit gates with trapped ions

Eduardo J. Páez, Seyed Shakib Vedaie, Barry C. Sanders·Jul 1, 2026

State-of-the-art two-qubit gates with trapped ions employ open-loop control that rely on simplified models to precompute control sequences. Our aim is to introduce closed-loop control for two-qubit gates to correct disturbances as they occur during t...

Subsystem Thermalization and Work Statistical Characterizations of Floquet Dynamics

Feng-Li Lin, Ching-Yu Huang·Jul 1, 2026

We study Floquet thermalization in a periodically driven quantum non-integrable Ising chain by combining two operational diagnostics: subsystem thermalization and work statistics. For generic interacting Floquet systems, stroboscopic dynamics lead to...

Extreme volume monogamy via bound-state engineering

Wen-Jie Zhang, Jun-Hong An·Jul 1, 2026

Quantum steering ellipsoid (QSE) provides a faithful representation of a two-qubit state. When extended to tripartite systems, the steerability from a trusted party to different receivers is subject to volume monogamy relations, which only constrain ...

Wallis Products from the Four-Dimensional Singular Harmonic Oscillator

Bin Ye, Ruitao Chen, Lei Yin·Jul 1, 2026

We present a variational derivation of the Wallis product and its reciprocal from the four-dimensional singular harmonic oscillator. The inverse-square interaction is absorbed into an effective angular parameter $ν$, so that the lowest exact energy i...
