Absolutely maximally entangled pure states of multipartite quantum systems
Grzegorz Rajchel-MieldzioÄ, RafaÅ BistroÅ, Albert Rico +2
Absolutely maximally entangled (AME) pure states of a system composed of parties are distinguished by the property that for any splitting at least one partial trace is maximall…
Entangling power and fidelity diagnostic for bipartite quantum channels
Marcin RudziÅski, Gianluigi Tartaglione, Karol Å»yczkowski
We study two complementary diagnostics of bipartite quantum channels, namely fidelity preservation across different classes of input states and entanglement generation from product…
Graph restricted tensors: building blocks for holographic networks
Rafaĺ BistroÅ, Márton Mestyán, Balázs Pozsgay +1
We analyze few-body quantum states with particular correlation properties imposed by the requirement of maximal bipartite entanglement for selected partitions of the system into tw…
Multipartite entanglement of random states of qubits
Giorgia Trotta, Paolo Scarafile, Paolo Facchi +5
We investigate multipartite entanglement via the statistical properties of pure quantum states of n-qubits. By analyzing the distribution of purity among balanced bipartitions, we…
Quantum Chaos and Quantum Information: Interactions and Implications
Arul Lakshminarayan, Karol Życzkowski
The notion of Shannon entropy is crucial for the theory of classical information. In quantum information theory, an analogous key role is played by the von Neumann entropy: quantum…
Quality assessment of quantum teleportation through the distribution of fidelity
D. G. Bussandri, G. M. Bosyk, P. Crespo Del Amo +1
In this work, we introduce a comprehensive statistical framework for assessing single-qubit quantum teleportation performance beyond the conventional average-fidelity benchmark. At…
