Certification of qubits in the prepare-and-measure scenario with large input alphabet and connections with the Grothendieck constant
Abstract We address the problem of testing the quantumness of two-dimensional systems in the prepare-and-measure (PM) scenario, using a large number of preparations and a large number of measurement settings, with binary outcome measurements. In this scenario, we introduce constants, which we relate...
