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…
Below-shot-noise capacity in phase estimation using nonlinear interferometers
Cristofero Oglialoro, Gerard J. Machado, Felix Farsch +7
Over the past decade, several schemes for imaging and sensing based on nonlinear interferometers have been proposed and demonstrated experimentally. These interferometers exhibit t…
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…
Benchmarking of Fluorescence Lifetime Measurements using Time-Frequency Correlated Photons
Tobias Bernd Gäbler, Nitish Jain, Patrick Then +3
The investigation of fluorescence lifetime became an important tool in biology and medical science. So far, established methods of fluorescence lifetime measurements require the il…
Enhancing entangled two-photon absorption of Nile Red via temperature-controlled SPDC
Aleksa KrstiÄ, Tobias Bernd Gäbler, Nitish Jain +6
Entangled two-photon absorption can enable a linear scaling of fluorescence emission with the excitation power. In comparison to classical two-photon absorption with a quadratic sc…
