报告题目:Three-outcome Bell inequalities tailored to SU3 many-body systems报 告 人:Guillem Müller Rigat (ICFO)报告时间:2025年7月1日10:00报告地点:物理楼W260报告简介:We present a three-outcome Bell inequality which we show to be naturally suited to explore non-local correlations in many-body spin-1 systems or SU(3) models. From such an inequality, we show how simple bounds on single-particl...
