Query: Multiplicativity of Accessible Fidelity and Quantumness for Sets of
  Quantum States   Two measures of sensitivity to eavesdropping for alphabets of quantum states
were recently introduced by Fuchs and Sasaki in quant-ph/0302092. These are the
accessible fidelity and quantumness. In this paper we prove an important
property of both measures: They are multiplicative under tensor products. The
proof in the case of accessible fidelity shows a connection between the measure
and characteristics of entanglement-breaking quantum channels.
