ePrint ReportHere we present new constructions for OTM\'s using isolated qubits, which improve on previous work in several respects: they achieve a stronger \"single-shot\" security guarantee, which is stated in terms of the (smoothed) min-entropy; they are proven secure against adversaries who can perform arbitrary local operations and classical communication (LOCC); and they are efficiently implementable.
These results use Wiesner\'s idea of conjugate coding, combined with error-correcting codes that approach the capacity of the q-ary symmetric channel, and a high-order entropic uncertainty relation, which was originally developed for cryptography in the bounded quantum storage model.
