Phys. Rev. A 64, 042316 (2001) [5 pages]Inconclusive rate in quantum key distributionReceived 1 June 2001; published 18 September 2001 After summarizing a recent calculation of the maximum Renyi information loss (for fixed error and inconclusive rates) from a positive operator valued measure (POVM) quantum cryptographic receiver to a general unitary probe, I calculate the worst inconclusive rate for the legitimate receiver. Disturbed inconclusive rates are considered which are less, as well as greater, than the unperturbed inconclusive rate. I also demonstrate that for an optimized individual attack there is a minimum induced error rate which is fixed by the induced inconclusive rate. © 2001 The American Physical Society URL:
