Entanglement versus Bell violations and their behaviour under local filtering operations
Frank Verstraete, Michael M. Wolf
We discuss the relations between the violation of the CHSH Bell inequality for systems of two qubits on the one side and entanglement of formation, local filtering operations, and…
Four qubits can be entangled in nine different ways
F. Verstraete, J. Dehaene, B. De Moor +1
We consider a single copy of a pure four-partite state of qubits and investigate its behaviour under the action of stochastic local quantum operations assisted by classical communi…
The Lorentz singular value decomposition and its applications to pure states of 3 qubits
Frank Verstraete, Jeroen Dehaene, Bart De Moor
All mixed states of two qubits can be brought into normal form by the action of SLOCC operations of the kind . These normal forms can be obtai…
A comparison of the entanglement measures negativity and concurrence
Frank Verstraete, Koenraad Audenaert, Jeroen Dehaene +1
In this paper we investigate two different entanglement measures in the case of mixed states of two qubits. We prove that the negativity of a state can never exceed its concurrence…
On the geometry of entangled states
Frank Verstraete, Jeroen Dehaene, Bart De Moor
The basic question that is addressed in this paper is finding the closest separable state for a given entangled state, measured with the Hilbert Schmidt distance. While this proble…
Normal forms and entanglement measures for multipartite quantum states
Frank Verstraete, Jeroen Dehaene, Bart De Moor
A general mathematical framework is presented to describe local equivalence classes of multipartite quantum states under the action of local unitary and local filtering operations.…
Sensitivity optimization in quantum parameter estimation
F. Verstraete, A. C. Doherty, H. Mabuchi
We present a general framework for sensitivity optimization in quantum parameter estimation schemes based on continuous (indirect) observation of a dynamical system. As an illustra…
