Resource-efficient high-dimensional entanglement detection via symmetric projections
Simon Morelli, Marcus Huber, Armin Tavakoli
We introduce two families of criteria for detecting and quantifying the entanglement of a bipartite quantum state of arbitrary local dimension. The first is based on measurements i…
Correlation constraints and the Bloch geometry of two qubits
Simon Morelli, Christopher Eltschka, Marcus Huber +1
We present a novel inequality on the purity of a bipartite state depending solely on the difference of the local Bloch vector lengths. For two qubits this inequality is tight for a…
Entanglement detection with imprecise measurements
Simon Morelli, Hayata Yamasaki, Marcus Huber +1
We investigate entanglement detection when the local measurements only nearly correspond to those intended. This corresponds to a scenario in which measurement devices are not perf…
Metrology-assisted entanglement distribution in noisy quantum networks
Simon Morelli, David Sauerwein, Michalis Skotiniotis +1
We consider the distribution of high-dimensional entangled states to multiple parties via noisy channels and the subsequent probabilistic conversion of these states to desired targ…
Activation of genuine multipartite entanglement: Beyond the single-copy paradigm of entanglement characterisation
Hayata Yamasaki, Simon Morelli, Markus Miethlinger +3
Entanglement shared among multiple parties presents complex challenges for the characterisation of different types of entanglement. One of the most fundamental insights is the fact…
The shape of higher-dimensional state space: Bloch-ball analog for a qutrit
Christopher Eltschka, Marcus Huber, Simon Morelli +1
Geometric intuition is a crucial tool to obtain deeper insight into many concepts of physics. A paradigmatic example of its power is the Bloch ball, the geometrical representation…
