Experimental implementation of dimension-dependent contextuality inequality
Emil Håkansson, Amelie Piveteau, Alban Seguinard +4
We present a derivation and experimental implementation of a dimension-dependent contextuality inequality to certify both the quantumness and dimensionality of a given system. Exis…
Superactivation and Incompressibility of Genuine Multipartite Entanglement
Lisa T. Weinbrenner, Klára Baksová, Sophia Denker +4
Quantum correlations in the form of entanglement, quantum steering or Bell nonlocality are resources for various information-processing tasks, but their detailed quantification and…
Real randomized measurements for analyzing properties of quantum states
Jin-Min Liang, Satoya Imai, Shuheng Liu +3
Randomized measurements are useful for analyzing quantum systems especially when quantum control is not fully perfect. However, their practical realization typically requires multi…
Reference-frame-independent quantum metrology
Satoya Imai, Otfried Gühne, Géza Tóth
How can we perform a metrological task if only limited control over a quantum system is given? Here, we present systematic methods for conducting nonlinear quantum metrology in sce…
Optimal Overlapping Tomography
Kiara Hansenne, Rui Qu, Lisa T. Weinbrenner +7
Characterising large-scale quantum systems is central to fundamental physics and essential for applications of quantum technologies. While a full characterisation requires exponent…
Quantifying information flow in quantum processes
Leonardo S. V. Santos, Zhen-Peng Xu, Jyrki Piilo +1
We present a framework for quantifying information flow within general quantum processes. For this purpose, we introduce the signaling power of quantum channels and discuss its rel…
