Bounds on $k$ -Uniform Quantum States

Fei Shi, Yu Ning, Qi Zhao +1

Do $N$ -partite $k$ -uniform states always exist when $k \leq ⌊ \frac{N}{2} ⌋ - 1$ ? In this work, we provide new upper bounds on the parameter $k$ for the existence of $k$ -uni…

Unextendible product bases from orthogonality graphs

Fei Shi, Ge Bai, Xiande Zhang +2

Unextendible product bases (UPBs) play a key role in the study of quantum entanglement and nonlocality. A famous open question is whether there exist genuinely unextendible product…
