Markov triplets on CCR-algebras
Anna Jencova, Denes Petz, Jozsef Pitrik
The paper contains a detailed computation about the algebra of canonical commutation relation, the representation of the Weyl unitaries, the quasi-free states and their von Neumann…
Three-Qubit Operators, the Split Cayley Hexagon of Order Two and Black Holes
Peter Levay, Metod Saniga, Peter Vrana
The set of 63 real generalized Pauli matrices of three-qubits can be factored into two subsets of 35 symmetric and 28 antisymmetric elements. This splitting is shown to be complete…
Hypothesis testing for Gaussian states on bosonic lattices
Milan Mosonyi
The asymptotic state discrimination problem with simple hypotheses is considered for a cubic lattice of bosons. A complete solution is provided for the problems of the Chernoff and…
Three fermions with six single particle states can be entangled in two inequivalent ways
Péter Lévay, Péter Vrana
Using a generalization of Cayley's hyperdeterminant as a new measure of tripartite fermionic entanglement we obtain the SLOCC classification of three-fermion systems with six singl…
Environment Induced Bipartite Entanglement
Fabio Benatti, Alexandra M. Liguori, Adam Nagy
Recently, a sufficient condition on the structure of the Kossakowski-Lindblad master equation has been given such that the generated reduced dynamics of two qubits results entangli…
On the geometry of four qubit invariants
Péter Lévay
The geometry of four-qubit entanglement is investigated. We replace some of the polynomial invariants for four-qubits introduced recently by new ones of direct geometrical meaning.…
