A study of two-qubit density matrices with fermionic purifications
Szilárd Szalay, Péter Lévay, Szilvia Nagy +1
We study 12 parameter families of two qubit density matrices, arising from a special class of two-fermion systems with four single particle states or alternatively from a four-qubi…

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…
