Setup for the QCE task where both the encoder and decoder have a single memory mode. The matrices \({\textbf{O}}_\text {enc}\) and \({\textbf{O}}_\text {dec}\) are decomposed using beam splitters (BS) and phase shifters (PS). A squeezer (S) is used to generate input states, while the output states are measured using a photon-number-resolving (PNR) detector. As the PSs outside of the loops do not influence the PNR results, they can be disregarded.
