We show that if an eavesdropper performs a coherent measurement on many quantum ancilla states simultaneously, classical methods of secure key distillation are less effective than quantum entanglement distillation protocols. We also show that certain classes of Bell diagonal states are resistant to any attempt at incoherent eavesdropping. © 2005 The American Physical Society.||Source Title:||Physical Review A - Atomic, Molecular, and Optical Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/97711||ISSN:||10502947||DOI:||10.1103/PhysRevA.71.012309|
