Distributed Entanglement
Consider three qubits A, B, and C which may be entangled with each other. We show that there is a trade-off between A’s entanglement with B and its entanglement with C. This relation is expressed in terms of a measure of entanglement called the “tangle,” which is related to the entanglement of formation. Specifically, we show that the tangle between A and B, plus the tangle between A and C, can...
متن کاملDistributed Compression and Squashed Entanglement
A single quantum state can be shared by many distant parties. In this thesis, we try to characterize the information contents of such distributed states by defining the multiparty information and the multiparty squashed entanglement, two steps toward a general theory of multiparty quantum information. As a further step in that direction, we partially solve the multiparty distributed compression...
متن کاملMulti-distributed entanglement in finitely correlated chains
– The entanglement-sharing properties of an infinite spin-chain are studied when the state of the chain is a pure, translation-invariant state with a matrix-product structure [1]. We study the entanglement properties of such states by means of their finitely correlated structure [2]. These states are recursively constructed by means of an auxiliary density matrix ρ on a matrix algebra B and a c...
متن کاملDistributed Compression and Multiparty Squashed Entanglement
We study a protocol in which many parties use quantum communication to transfer a shared state to a receiver without communicating with each other. This protocol is a multiparty version of the fully quantum Slepian-Wolf protocol for two senders and arises through the repeated application of the two-sender protocol. We describe bounds on the achievable rate region for the distributed compression...
متن کاملDistributed Sources, Accelerated Universe, Consciousness and Quantum Entanglement
It is shown that such diverse phenomena as accelerated Universe, consciousness and quantum entanglement are connected by the concept of distributed sources and imaginary (particularly, tachyon) fields. The singular vortices, sources (sinks) and vortex-sinks are well known models in fluid dynamics (including geophysical fluid dynamics), magnetized plasma, superfluidity and superconductivity (see...
