Query: Digital quantum simulation of beam splitters and squeezing with IBM
  quantum computers   We present results on the digital quantum simulations of beam-splitter and
squeezing interactions. The bosonic hamiltonians are mapped to qubits and then
digitalized in order to implement them in the IBM quantum devices. We use error
mitigation and post-selection to achieve high-fidelity digital quantum
simulations of single-mode and two-mode interactions, as evidenced -- where
possible -- by full tomography of the resulting states. We achieve fidelities
above 90 \% in the case of single-mode squeezing with low squeezing values and
ranging from 60 \% to 90 \% for large squeezing and in the more complex
two-mode interactions.
