Composite anyon coding and the initialization of a topological quantum computer
Robert Koenig
Schemes for topological quantum computation are usually based on the assumption that the system is initially prepared in a specific state. In practice, this state preparation is ex…

A strong converse for classical channel coding using entangled inputs
Robert Koenig, Stephanie Wehner
A fully general strong converse for channel coding states that when the rate of sending classical information exceeds the capacity of a quantum channel, the probability of correctl…

Simplifying quantum double Hamiltonians using perturbative gadgets
Robert Koenig
Perturbative gadgets were originally introduced to generate effective k-local interactions in the low-energy sector of a 2-local Hamiltonian. Extending this idea, we present gadget…
