Tight security bounds for quantum key distribution

[63] The present study is about charge transport in ultra-small NP SA in the Coulomb blockade regime, but polarizability can definitely be considered in other

This approach effectively defines three separate network planes, a quantum plane (quantum channels and QKD devices which push key to the node-modules), secret’s plane (node- modules

Instead, results showed that, keeping zero heel to toe drop, midsole thickness did not affect foot strike pattern but that foot strike patterns were different between barefoot and

It has been shown that in the asymptotic case of infinite-key length, the 2-decoy state Quantum Key Distribution (QKD) protocol outperforms the 1-decoy state protocol. Here, we

One interesting example illustrating the strength of our technique is the BB84 protocol or the six-state protocol, where, in the classical processing step, Alice additionally adds

Lower and Upper Bounds on the Secret-Key Rate for Quantum Key Distribution Protocols Using One-Way Classical Communication.. KRAUS, Barbara, GISIN, Nicolas,

The evaluation shows that our security bounds are relatively tight, in the sense that for realistic postprocessing block sizes, the achievable secret key rates are comparable to

To obtain our results for finite block sizes n, we fix a security bound and define an optimized -secure protocol, Φ ∗ [n, ], that results from a maximization of the expected secret
