Single Spatio-Temporal Mode Bright Twin-Beam Source Across the Near- and Mid-Infrared
Gabriel Demontigny, Patrick Cusson, Amauri Perraton Elorza +6
We introduce an ultrafast, bright, entangled twin-beam source generated by type-0 parametric down-conversion in periodically-poled lithium niobate at MHz repetition rate, with cont…
Kerr-induced non-Gaussianity of ultrafast bright squeezed vacuum
Andrei Rasputnyi, Ilya Karuseichyk, Gerd Leuchs +2
Non-Gaussian states of light are a critical resource for fault-tolerant quantum computing and enhanced metrology, but are typically faint and often obtained via post-selection. Her…
Real-Time Monitoring of Multimode Squeezing
Mahmoud Kalash, Aditya Sudharsanam, M. H. M. Passos +2
Multimode squeezed light is a key resource for high-dimensional quantum technologies, enhancing metrological sensitivity, boosting communication security, and enabling parallel pro…
Efficient detection of spectrally multimode squeezed light through optical parametric amplification
Mahmoud Kalash, Ui-Nyung Han, Young-Sik Ra +1
Multimode squeezed light is a key resource for high-dimensional photonic quantum technologies, enabling applications in quantum-enhanced sensing, quantum communication, and quantum…
Driving electrons at needle tips strongly with quantum light
Jonas Heimerl, Andrei Rasputnyi, Jonathan Pölloth +3
Attosecond science relies on driving electrons after photoemission with the strong optical field of a laser pulse, representing an intense classical coherent state of light. Bright…
Tunable N-level EIT: Deterministic Generation of Optical States with Negative Wigner Function
Sutapa Ghosh, Alexey Gorlach, Chen Mechel +3
Strong optical nonlinearities are key to a range of technologies, particularly in the generation of photonic quantum states. The strongest nonlinearity in hot atomic vapors origina…
