Memory and thermal amplification in spin--cavity squared commutators
Yong-Hong Ma, Hui-Hui Xu, Jian-Zhuang Wu +4
Squared commutators in the Holstein--Primakoff limit of a spin--cavity system provide a compact way to separate propagation from covariance growth in a finite-temperature reservoir…

The Power of Two Bases: Robust and copy-optimal certification of nearly all quantum states with few-qubit measurements
Andrea Coladangelo, Jerry Li, Joseph Slote +1
A central task in quantum information science is state certification: testing whether an unknown state is -close to a fixed target state, or -far. Recent work has shown…
