Spectrally-resolved four-photon interference of time-frequency entangled photons
Sofiane Merkouche, Valérian Thiel, Brian J. Smith
Pairs of photons entangled in their time-frequency degree of freedom are of great interest in quantum optics research and applications, due to their relative ease of generation and…
Quantifying the enhancement of two-photon absorption due to spectral-temporal entanglement
Tiemo Landes, Michael G. Raymer, Markus Allgaier +3
When a low flux of time-frequency-entangled photon pairs (EPP) illuminates a two-photon transition, the rate of two-photon absorption (TPA) can be enhanced considerably by the quan…
Heralding multiple photonic pulsed Bell-pairs via frequency-resolved entanglement swapping
Sofiane Merkouche, Valérian Thiel, Alex O. C. Davis +1
Entanglement is a unique property of quantum systems and an essential resource for many quantum technologies. The ability to transfer or swap entanglement between systems is an imp…
A positive operator-valued measure for two-photon detection via sum-frequency generation
Sofiane Merkouche, Valérian Thiel, Brian J. Smith
Spontaneous parametric down conversion (PDC), in the perturbative limit, can be considered as a probabilistic splitting of one input photon into two output photons. Conversely, sum…
Experimental feasibility of molecular two-photon absorption with isolated time-frequency-entangled photon pairs
Tiemo Landes, Markus Allgaier, Sofiane Merkouche +3
Entangled photon pairs have been promised to deliver a substantial quantum advantage for two-photon absorption spectroscopy. However, recent work has challenged the previously repo…
Two-photon absorption of time-frequency-entangled photon pairs by molecules: the roles of photon-number correlations and spectral correlations
Michael G. Raymer, Tiemo Landes, Markus Allgaier +3
While two-photon absorption (TPA) and other forms of nonlinear interactions of molecules with isolated time-frequency-entangled photon pairs (EPP) have been predicted to display a…
Gaussian versus non-Gaussian filtering of phase-insensitive nonclassicality
Benjamin Kühn, Werner Vogel, Valérian Thiel +2
Measures of quantum properties are essential to understanding the fundamental differences between quantum and classical systems as well as quantifying resources for quantum technol…
Two-color Bell states heralded via entanglement swapping
Sofiane Merkouche, Valérian Thiel, Alex O. C. Davis +1
We report on an experiment demonstrating entanglement swapping of time-frequency entangled photons. We perform a frequency-resolved Bell-state measurement on the idler photons from…
