Experimental Test of Contextuality Based on State Discrimination with a Single Qubit
文献摘要：
Exploring quantum phenomena beyond predictions of any classical model has fundamental importance to understand the boundary of classical and quantum descriptions of nature.As a typical property that a quantum system behaves distinctively from a classical counterpart,contextuality has been studied extensively and verified experimentally in systems composed of at least three levels(qutrit).Here we extend the scope of experimental test of contextuality to a minimal quantum system of only two states(qubit)by implementing the minimum error state discrimination on a single 171 Yb+ion.We observe a substantial violation of a no-go inequality derived by assuming non-contextuality,and firmly conclude that the measured results of state discrimination cannot be reconciled with any non-contextual description.We also quantify the contextual advantage of state discrimination and the tolerance against quantum noises.
