    "abstract": "Two measures of sensitivity to eavesdropping for alphabets of quantum states\nwere recently introduced by Fuchs and Sasaki in quant-ph/0302092. These are the\naccessible fidelity and quantumness. In this paper we prove an important\nproperty of both measures: They are multiplicative under tensor products. The\nproof in the case of accessible fidelity shows a connection between the measure\nand characteristics of entanglement-breaking quantum channels.",
