In our new work, we prove that under minimal constraints on the physicality of a Wigner function, all states with purity μ<2/e satisfy the conjecture. Since we consider Wigner functions that are not necessarily physical, our results does not provide a negative answer to the conjecture. However, we find a large family of states that…

Qipeng Qian published his first paper under my supervision (Qipeng has also published other works in the past). Congratulations, Qipeng! Our paper pertains to the newly introduced notion of Wigner entropy. You can read the arXiv version here and the published version here.
