Query: Self-testing quantum states and measurements in the prepare-and-measure
  scenario   The goal of self-testing is to characterize an a priori unknown quantum
system based solely on measurement statistics, i.e. using an uncharacterized
measurement device. Here we develop self-testing methods for quantum
prepare-and-measure experiments, thus not necessarily relying on entanglement
and/or violation of a Bell inequality. We present noise-robust techniques for
self-testing sets of quantum states and measurements, assuming an upper bound
on the Hilbert space dimension. We discuss in detail the case of a $2
\rightarrow 1$ random access code with qubits, for which we provide
analytically optimal self-tests. The simplicity and noise robustness of our
methods should make them directly applicable to experiments.
