Almost qudits in the prepare-and-measure scenario
Quantum communication is often investigated in scenarios where only the dimension of
Hilbert space is known. However, assigning a precise dimension is often an approximation …

Positive operator-valued measure for two-photon detection via sum-frequency generation
Spontaneous parametric down conversion (PDC), in the perturbative limit, can be
considered as a probabilistic splitting of one input photon into two output photons …
