Quantum sampling in hybrid light-matter systems with mixed statistics
Franziska Barkhausen, Laura Ares, Stefan Schumacher +1
Boson sampling is one of the most prominent methods to verify quantum advantage, harnessing the computational complexity of the permanent of a network matrix. Similar quantum sampl…
Bounding Kirkwood-Dirac negativity of Gaussian processes
Luca Bianchi, Carlo Marconi, Riccardo Cioli +1
The Kirkwood-Dirac quasiprobability provides an operational representation of a quantum state, whose negativity serves as a measure of nonclassicality. Despite its fundamental impo…
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,…
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…
Universal entanglement-inspired correlations
Elizabeth Agudelo, Laura Ares, Jan Sperling
Quantum correlations, crucial for the advantage and advancement of quantum science and technology, arise from the impossibility of expressing a quantum state as a tensor product ov…
Numerical approaches to entangling dynamics from variational principles
Christian Offen, Boris Wembe, Laura Ares +2
In this work, we address the numerical identification of entanglement in dynamical scenarios. To this end, we consider different programs based on the restriction of the evolution…
