Classical Protocols and Quantum Privacy Ampli cation Sample Clauses

Classical Protocols and Quantum Privacy Ampli cation jXj jYj X Y It is a natural question whether the analogy between entanglement and intrinsic information (see Section 3.1) carries over to the protocol level. The examples given in Section 3.5 support this belief. A quite interesting and surprising conse- quence would be that there exists a classical counterpart to bound entanglement, namely intrinsic information that cannot be distilled into a secret key by any classical protocol, if + > 5, where and are the ranges of X and Y , respectively. In other words, the conjecture in [22] that such information can i.e., AB is free entangled. AB, i.e., AB is bound entangled or separable.
