Bounding Kirkwood-Dirac negativity of Gaussian processes
Luca Bianchi, Carlo Marconi, Riccardo Cioli +1
The paper derives upper and lower bounds on the negativity of the Kirkwood‑Dirac quasiprobability for quantum states undergoing Gaussian processes, showing that Gaussian states can…
Demonstration of unpartible entanglement
Philip Held, Laura Ares, Federico Pegoraro +4
We report on the first experimental verification of mode-independent entanglement. Commonly, the entanglement of a state is firmly based on pre-defined parties that are correlated,…
Assessing the classicality of photon echo from excitons in lead halide perovskite nanocrystals
George Alkhalil, Hendrik Rose, Artur V. Trifonov +9
Photon echo (PE) spectroscopy is a powerful technique for probing decoherence mechanisms and charge carrier dynamics in semiconductor systems. Beyond traditional coherence measurem…
Resource-efficient universal photonic processor based on time-multiplexed hybrid architectures
Jonas Lammers, Laura Ares, Federico Pegoraro +4
For the ever-growing field of quantum information processing, large-scale, efficient multi-port interferometers serving as photonic processors are required. In this context, the su…
Learning to detect optical nonclassicality
Martina Jung, Suchitra Krishnaswamy, Timon Schapeler +4
Nonclassicality, defined in the quantum optical sense, serves as a resource for photon-based quantum technologies. Therefore, certifying the nonclassicality of a quantum state is c…
Observable nonclassicality witnesses for multiplexed detection systems
Suchitra Krishnaswamy, Martina Jung, Laura Ares +2
We address the problem of constructing witnesses for nonclassical light that are applicable in state-of-the-art photon-counting devices. The key ingredient for the criteria we deri…
