Monogamy, Polygamy and other Properties of Entanglement of Purification
For bipartite pure and mixed quantum states, in addition to the quantum mutual information, there is another measure of total correlation, namely, the entanglement of purification. We study the monogamy, polygamy, and additivity properties of the entanglement of purification for pure and mixed states. In this paper, we show that, in contrast to the quantum mutual information which is strictly m...
متن کاملMonogamy and Polygamy of Entanglement in Multipartite Quantum Systems
One distinct property of quantum entanglement from other classical correlations is that multipartite entanglements cannot be freely shared among the parties: If two parties in a multi-party system share a maximally entangled state, then they cannot share any entanglement with the rest. This is known as monogamy of entanglement (MoE) [1], which is a key ingredient for secure quantum cryptography...
متن کاملDistributed 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 کاملThe Mystery of Polygamy
The economic literature on marriage identifies a number of benefits of marriage and discusses mechanisms that cause societies to prefer certain marital structures such as polygyny or monogamy. In principle, however, these benefits and mechanisms might lead societies towards polyandry and even cenogamy. The rareness of polyandry and the absence of cenogamy, however, clearly indicate that importa...
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...
