Advances in Position-Momentum Entanglement: A Versatile Tool for Quantum Technologies
Satyajeet Patil, Sebastian Töpfer, Rajshree Swarnkar +4
Position-momentum entanglement is a versatile high-dimensional resource in quantum optics. From fundamental tests of reality to applications in quantum technologies, spatial entang…
Vectorial field reconstruction without detecting the field
Jonas Vasikonis, Sebastian Töpfer, Satyajeet Patil +2
Vector beams, whose polarization varies across the transverse profile, are a central resource in structured-light optics and quantum photonics. Their characterization, however, bec…
Non-degenerate SPDC photon-pair source for UV-A illumination
Preetisha Goswami, Marta Gilaberte Basset, Jorge Fuenzalida +2
We present a frequency-correlated non-degenerate photon-pair source consisting of a second-order nonlinear crystal that generates ultraviolet UV-A and infrared light via spontaneou…
Visibility Stokes parameters as a foundation for quantum information science with undetected photons
Jaroslav Kysela, Markus Gräfe, Jorge Fuenzalida
The framework of measurement operators plays a fundamental role in extracting information about quantum systems. Recently, techniques based on induced coherence have been developed…
Synthetic Quantum Holography with Undetected Light
Sebastian Töpfer, Sergio Tovar, Josué R. León Torres +4
Utilizing nonlinear interferometers for sensing with undetected light enables new sensing and imaging techniques in spectral ranges that are difficult to detect. To enhance this me…
Polarization-entangled photon pair source using beam displacers and thin crystals
Minjae Hong, Rodrigo Gomez, Valerio Flavio Gili +2
We present an experimental implementation of a polarization-entangled photon pair source based on beam displacers. The down-converted photons are emitted via spontaneous parametric…
