The Veldkamp space of multiple qubits
Péter Vrana, Péter Lévay
We introduce a point-line incidence geometry in which the commutation relations of the real Pauli group of multiple qubits are fully encoded. Its points are pairs of Pauli operator…
Special entangled quantum systems and the Freudenthal construction
Péter Vrana, Péter Lévay
We consider special quantum systems containing both distinguishable and identical constituents. It is shown that for these systems the Freudenthal construction based on cubic Jorda…
Black Hole Entropy and Finite Geometry
Péter Lévay, Metod Saniga, Péter Vrana +1
It is shown that the symmetric entropy formula describing black holes and black strings in D=5 is intimately tied to the geometry of the generalized quadrangle GQ…
The Veldkamp Space of GQ(2,4)
Metod Saniga, Richard M. Green, Peter Levay +2
It is shown that the Veldkamp space of the unique generalized quadrangle GQ(2,4) is isomorphic to PG(5,2). Since the GQ(2,4) features only two kinds of geometric hyperplanes, namel…
