The exact LCU sampling overhead of collective diagonal unitaries: resonances and a continued-fraction dichotomy

The minimal sampling overhead of the quadratic collective phase $e^{-i\gamma K^2}$ over one layer of single-qubit rotations is decided by the continued fraction of $\gamma/\pi$. Here $K$ is a collective observable with spectrum $\{0,\dots,n\}$, such as the permutation-symmetric Hamming weight. This gate is the cardinal...

Structured Quantum Kernels for Chaotic Forecasting

A quantum kernel fusing amplitude encoding of l2-normalized delay windows with a grouped single-qubit rotation layer that assigns contiguous temporal blocks to each qubit, making the circuit delay-window-aware and the first mechanistic localisation of quantum-kernel advantage to a specific dynamical regime of a classic...
