“Squashed entanglement”: An additive entanglement measure [PDF]
Journal of Mathematical Physics, 2004 In this paper, we present a new entanglement monotone for bipartite quantum states. Its definition is inspired by the so-called intrinsic information of classical cryptography and is given by the halved minimum quantum conditional mutual information over all tripartite state extensions.

Control of entanglement and the high-entanglement limit
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2003We examine two-particle entanglement and ways in which it might be coherently controlled. Control is desirable for successful implementation of quantum computing. As one result, we find that reaching very high entanglement may be feasible experimentally.

Entanglement Persistency of Multiphoton Entangled States
Physical Review Letters, 2006We experimentally demonstrate the entanglement persistency when losing photons in three- and four-photon polarization-entangled states. The entanglement properties of the mixed states obtained from multiphoton spontaneous parametric down-conversion are studied via witness and positive partial transpose approaches.

Quantum Information and Computation, 2002
We study how bi-partite quantum entanglement (measured in terms of a concurrence) can be shared in multi-qubit systems. We introduce a concept of the entangled graph such that each qubit of a multi-partite system is associated with a vertex while a bi-partite entanglement between two specific qubits is represented by an edge.

Reply to “Comment on ‘Entangled entanglement’ ”
Physical Review A, 1997In our paper @1# we consider a three-particle system described by the Greenberger-Horne-Zeilinger state @2,3# proposed by Mermin @4#. Spin measurements with two possible outcomes (1 and 2) are performed on the particles along arbitrary directions. By the results of the measurements on one particle, say, particle 3, two subensembles of the results of ...

Serendipity as Entanglement: Entanglement as Serendipity
This thesis offers serendipity researchers a novel approach for interpreting artefacts, making processes and serendipitous outcomes by using theories of entanglement. Whilst the author draws from understandings that have been built up from their experiences as a maker, they write from a position of awareness that some idea of serendipity, embedded in ...openaire +1 more source
