Alternating Squeezing and Photon Subtraction for Optical Cat-State Generation
Johanna Conrad, Fabian Steinlechner, René Sondenheimer
Schrödinger cat states are important non-Gaussian resources for quantum information processing and quantum-enhanced metrology. Although photon subtraction from squeezed vacuum stat…
Loss-aware pulse sequence optimization for generating photonic Fock states
Benjamin Stodd, Priyanshu Tiwari, René Sondenheimer +2
We investigate the preparation of frequency-tunable photonic Fock states in a hybrid cavity system consisting of a nonlinear medium and a two-level system. Employing a gradient-bas…
Multipartite entanglement dynamics in quantum walks
Emil K. F. Donkersloot, René Sondenheimer, Jan Sperling
Quantum walks constitute a rich area of quantum information science, where multipartite entanglement plays a central role in the dynamics and scalability of quantum advantage over…
Optimizing photon-number distributions of Gaussian states in the presence of loss: Towards minimizing the impact of loss in Gaussian boson sampling
Hendrik Ellenberg, René Sondenheimer
We analyze the impact of photon loss on the photon-number statistics of Gaussian states. Specifically, we propose and carefully evaluate several methods to mitigate deviations in t…
Certifying spatial entanglement between non-degenerate photon pairs with a camera
Emma Brambila, Raphael Guitter, René Sondenheimer +2
We investigate transverse spatial entanglement between photon pairs of different wavelengths using a camera-based coincidence technique. By adapting the correlation measurements to…
Experimental analysis on image resolution of quantum imaging with undetected light through position correlations
Marta Gilaberte Basset, René Sondenheimer, Jorge Fuenzalida +7
Image resolution of quantum imaging with undetected photons is governed by the spatial correlations existing between the photons of a photon pair that has been generated in a nonli…
