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,…
Quantum speedup from nonclassical polarization
Tim AÃbrock, Jan Sperling, Laura Ares
We develop a framework for identifying nonclassical speedups in systems with polarization, likewise spin degrees of freedom. By confining the dynamics to the manifold of angular mo…
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…
Benchmarking Gaussian and non-Gaussian input states with a hybrid sampling platform
Michael Stefszky, Kai-Hong Luo, Jan-Lucas Eickmann +22
The original boson sampling paradigm-consisting of multiple single-photon input states, a large interferometer, and multi-channel click detection-was originally proposed as a photo…
Quantifying entanglement in quantum thermodynamics via separability constraints
Joan Alba, Laura Ares, Jan Sperling +1
The role of quantum entanglement in thermodynamical systems remains elusive. Does entanglement result in thermodynamic advantages or does it impose fundamental limitations? Here, w…
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…
