Estimation of coherent error sources from stabilizer measurements
Davide Orsucci, Markus Tiersch, Hans J. Briegel
In the context of measurement-based quantum computation a way of maintaining the coherence of a graph state is to measure its stabilizer operators. Aside from performing quantum er…
Quantum walks on embedded hypercubes: Nonsymmetric and nonlocal cases
Adi Makmal, Markus Tiersch, Clemens Ganahl +1
The expected hitting time of discrete quantum walks on a hypercube (HC) is numerically known to be exponentially shorter than that of their classical analogs in terms of the scalin…
Coherent controlization using superconducting qubits
Nicolai Friis, Alexey A. Melnikov, Gerhard Kirchmair +1
Coherent controlization, i.e., coherent conditioning of arbitrary single- or multi-qubit operations on the state of one or more control qubits, is an important ingredient for the f…
Framework for learning agents in quantum environments
Vedran Dunjko, Jacob M. Taylor, Hans J. Briegel
In this paper we provide a broad framework for describing learning agents in general quantum environments. We analyze the types of classically specified environments which allow fo…
Measurement-based Quantum Communication
M. Zwerger, H. J. Briegel, W. Dür
We review and discuss the potential of using measurement-based elements in quantum communication schemes, where certain tasks are realized with the help of entangled resource state…
Faster quantum mixing for slowly evolving sequences of Markov chains
Davide Orsucci, Hans J. Briegel, Vedran Dunjko
Markov chain methods are remarkably successful in computational physics, machine learning, and combinatorial optimization. The cost of such methods often reduces to the mixing time…
