Absolutely maximally entangled (AME) states are maximally entangled for every bipartition
of the system. They are crucial resources for various quantum information protocols. We …

It is shown that the E 6 (6) symmetric entropy formula describing black holes and black
strings in D= 5 is intimately tied to the geometry of the generalized quadrangle GQ (2, 4) with …

We investigate the structure of the three-qubit magic Veldkamp line (MVL). This
mathematical notion has recently shown up as a tool for understanding the structures of the …

Quantum contextuality takes an important place amongst the concepts of quantum
computing that bring an advantage over its classical counterpart. For a large class of …

Abstract The development of Noisy Intermediate Scale Quantum Computers (NISQC)
provides for the Quantum Information community new tools to perform quantum experiences …

A bstract We invoke some ideas from finite geometry to map bijectively 135 heptads of
mutually commuting three-qubit observables into 135 symmetric four-qubit ones. After …

We introduce and describe a new heuristic method for finding an upper bound on the
degree of contextuality and the corresponding unsatisfied part of a quantum contextual …

We study the geometry of the space of Mermin pentagrams, objects that are used to rule out
the existence of noncontextual hidden variable theories as alternatives to quantum theory. It …

We study certain physically-relevant subgeometries of binary symplectic polar spaces W (2
N− 1, 2) of small rank N, when the points of these spaces canonically encode N-qubit …

There is an intriguing relation between quantum information theory and super gravity,
discovered by MJ Duff and S. Ferrara. It relates entanglement measures for qubits to black …
