Complete sets of cyclic mutually unbiased bases in even prime power dimensions
Oliver Kern, Kedar S. Ranade, Ulrich Seyfarth
We present a construction method for complete sets of cyclic mutually unbiased bases (MUBs) in Hilbert spaces of even prime power dimensions. In comparison to usual complete sets o…
Randomized Dynamical Decoupling Strategies and Improved One-Way Key Rates for Quantum Cryptography
Oliver Kern
The present thesis deals with various methods of quantum error correction. It is divided into two parts. In the first part, dynamical decoupling methods are considered which have t…
Stabilization of quantum information by combined dynamical decoupling and detected-jump error correction
Daniel Geberth, Oliver Kern, Gernot Alber +1
Two possible applications of random decoupling are discussed. Whereas so far decoupling methods have been considered merely for quantum memories, here it is demonstrated that rando…
Improved one-way rates for BB84 and 6-state protocols
Oliver Kern, Joseph M. Renes
We study the advantages to be gained in quantum key distribution (QKD) protocols by combining the techniques of local randomization, or noisy preprocessing, and structured (nonrand…
Selective recoupling and stochastic dynamical decoupling
O. Kern, G. Alber
An embedded selective recoupling method is proposed which is based on the idea of embedding the recently proposed deterministic selective recoupling scheme of Yamaguchi et al. [qua…
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…
