A Classical Analog to Entanglement Reversibility
In this letter we introduce the problem of secrecy reversibility. This asks when two honest parties can distill secret bits from some tripartite distribution pXY Z and transform secret bits back into pXY Z at equal rates using local operation and public communication (LOPC). This is the classical analog to the well-studied problem of reversibly concentrating and diluting entanglement in a quant...
متن کاملA Classical Analogy of Entanglement
A classical analogy of quantum mechanical entanglement is presented, using classical light beams. The analogy can be pushed a long way, only to reach its limits when we try to represent multiparticle, or nonlocal, entanglement . This demonstrates that the latter is of exclusive quantum nature . On the other hand, the entanglement of different degrees of freedom of the same particle might be con...
متن کاملClassical complexity and quantum entanglement
Generalizing a decision problem for bipartite perfect matching, Edmonds (J. Res. Natl. Bur. Standards 718(4) (1967) 242) introduced the problem (now known as the Edmonds Problem) of deciding if a given linear subspace ofM(N) contains a non-singular matrix, whereM(N) stands for the linear space of complexN ×N matrices. This problem led to many fundamental developments in matroid theory, etc. Cla...
متن کاملClassical information and distillable entanglement
We establish a quantitative connection between the amount of lost classical information about a quantum state and the concomitant loss of entanglement. Using methods that have been developed for the optimal purification of mixed states, we find a class of mixed states with known distillable entanglement. These results can be used to determine the quantum capacity of a quantum channel which rand...
متن کاملA classical view of quantum entanglement
This Master’s Thesis addresses the question of what is quantum entanglement. This question is of importance for engineering and information theory because of the possibility of quantum computing. Key to the answer of this question is the debate between Einstein and Bohr relating to this subject. Throughout this thesis the view of Einstein is given special and only consideration. It is appropria...
