Journal ArticleDOI
Relaxations of separability in multipartite systems: Semidefinite programs, witnesses and volumes
TL;DR: An operational witness construction arising from such relaxations that is capable of detecting every entangled state is described and it is proved that simple semi-definite relaxations in the multiparticle case cannot be an equally good approximation for any scenario.
Journal ArticleDOI
Experimental creation of multi-photon high-dimensional layered quantum states
Xiao-Min Hu,Wen-Bo Xing,Chao Zhang,Bi-Heng Liu,Matej Pivoluska,Matej Pivoluska,Marcus Huber,Yun-Feng Huang,Chuan-Feng Li,Guang-Can Guo +9 more
TL;DR: This work experimentally prepared a multipartite high-dimensional state and uses this quantum state to demonstrate a layered quantum network in principle, highlighting another route toward complex quantum networks.
Journal ArticleDOI
Measuring azimuthal and radial modes of photons.
Frédéric Bouchard,Natalia Herrera Valencia,Florian Brandt,Robert Fickler,Marcus Huber,Mehul Malik +5 more
TL;DR: A method to measure the azimuthal and radial modes of Laguerre-Gaussian beams with a greater than 99 % accuracy, using a single phase screen, and can be readily extended to any arbitrary family of spatial modes.
Journal ArticleDOI
Experimentally implementable criteria revealing substructures of genuine multipartite entanglement
Marcus Huber,Hans Schimpf,Andreas Gabriel,Christoph Spengler,Dagmar Bruß,Beatrix C. Hiesmayr,Beatrix C. Hiesmayr +6 more
TL;DR: A general framework that reveals substructures of genuine multipartite entanglement is presented that is beneficial regarding experimental examinations as only local measurements are required and the number of observables scales favorably with system size.
Journal ArticleDOI
Work estimation and work fluctuations in the presence of non-ideal measurements
TL;DR: In this article, the authors investigate the consequences for the estimation of work in non-equilibrium processes and for the fundamental structure of the work fluctuations when one assumes that the measurements are non-ideal.
