Smallest disentangling state spaces for general entangled bipartite quantum states
Hussain Anwar, Sania Jevtic, Oliver Rudolph +1
Entangled quantum states can be given a separable decomposition if we relax the restriction that the local operators be quantum states. Motivated by the construction of classical s…
Families of pure PEPS with efficiently simulatable local hidden variable models for most measurements
Hussain Anwar, Sania Jevtic, Oliver Rudolph +1
An important problem in quantum information theory is to understand what makes entangled quantum systems non-local or hard to simulate efficiently. In this work we consider situati…
Smallest state spaces for which bipartite entangled quantum states are separable
Hussain Anwar, Sania Jevtic, Oliver Rudolph +1
According to usual definitions, entangled states cannot be given a separable decomposition in terms of products of local density operators. If we relax the requirement that the loc…
On extremal quantum states of composite systems with fixed marginals
Oliver Rudolph
We study the convex set of all bipartite quantum states with fixed marginal states. The extremal states in this set have recently been characterized by Parthasarathy [Ann. Henri Po…
Some Properties of the Computable Cross Norm Criterion for Separability
Oliver Rudolph
The computable cross norm (CCN) criterion is a new powerful analytical and computable separability criterion for bipartite quantum states, that is also known to systematically dete…
A note on "A Matrix Realignment Method for Recognizing Entanglement," quant-ph/0205017 v1
Oliver Rudolph
In quant-ph/0205017 v1 Chen, Wu and Yang formulated a necessary separability criterion based on a realignment method for matrices. This note is to point out that this criterion is…
