- Abstract: Photon-pair correlations in spontaneous parametric down conversion are
ubiquitous in quantum photonics. The ability to engineer their properties for
optimising a specific task is essential, but often challenging in practice. We
demonstrate the shaping of spatial correlations between entangled photons in
the form of arbitrary amplitude and phase objects. By doing this, we encode
image information within the pair correlations, making it undetectable by
conventional intensity measurements. It enables the transmission of complex,
high-dimensional information using quantum correlations of photons, which can
be useful for developing quantum communication and imaging protocols.
