Asymptotic correctability of Bell-diagonal quantum states and maximum tolerable bit error rates
Kedar S. Ranade, Gernot Alber
The general conditions are discussed which quantum state purification protocols have to fulfill in order to be capable of purifying Bell-diagonal qubit-pair states, provided they c…
Security bound of two-bases quantum key-distribution protocols using qudits
Georgios M. Nikolopoulos, Gernot Alber
We investigate the security bounds of quantum cryptographic protocols using -level systems. In particular, we focus on schemes that use two mutually unbiased bases, thus extendi…
Controlling quantum systems by embedded dynamical decoupling schemes
Oliver Kern, Gernot Alber
A dynamical decoupling method is presented which is based on embedding a deterministic decoupling scheme into a stochastic one. This way it is possible to combine the advantages of…
Suppressing decoherence of quantum algorithms by jump codes
Oliver Kern, Gernot Alber
The stabilizing properties of one-error correcting jump codes are explored under realistic non-ideal conditions. For this purpose the quantum algorithm of the tent-map is decompose…
