Efficient decoupling schemes with bounded controls based on Eulerian orthogonal arrays
Pawel Wocjan
The task of decoupling, i.e., removing unwanted interactions in a system Hamiltonian and/or couplings with an environment (decoherence), plays an important role in controlling quan…
Equivalence of Decoupling Schemes and Orthogonal Arrays
Martin Roetteler, Pawel Wocjan
We consider the problem of switching off unwanted interactions in a given multi-partite Hamiltonian. This is known to be an important primitive in quantum information processing an…
New Construction of Mutually Unbiased Bases in Square Dimensions
Pawel Wocjan, Thomas Beth
We show that k=w+2 mutually unbiased bases can be constructed in any square dimension d=s^2 provided that there are w mutually orthogonal Latin squares of order s. The construction…
Ergodic quantum computing
Dominik Janzing, Pawel Wocjan
We propose a (theoretical ;-) model for quantum computation where the result can be read out from the time average of the Hamiltonian dynamics of a 2-dimensional crystal on a cylin…
Estimating mixing properties of local Hamiltonian dynamics and continuous quantum random walks is PSPACE-hard
Pawel Wocjan
A major topic of (classical) ergodic theory is to examine qualitatively how the phase space of dynamical systems is penetrated by the orbits of their dynamics. We consider interact…
