Keeping a Quantum Bit Alive by Optimized π-Pulse Sequences
TL;DR: A general strategy to maintain the coherence of a quantum bit is proposed based on an optimized pi-pulse sequence for dynamic decoupling extending the Carr-Purcell-Meiboom-Gill cycle.

TL;DR: The Roadmap on Magnonics as mentioned in this paper is a collection of 22 sections written by leading experts in this field who review and discuss the current status but also present their vision of future perspectives.
Journal ArticleDOI
Perturbation theory by flow equations: dimerized and frustrated S=1/2 chain
Christian Knetter,Götz S. Uhrig +1 more
TL;DR: In this article, the flow equation method is used as continuous unitary transformation to construct perturbatively effective Hamiltonians for antiferromagnetic S ≥ 1/2 chains and the gap, dispersion and ground state energies of the chains are provided.
Journal ArticleDOI
Exact results on dynamical decoupling by π pulses in quantum information processes
TL;DR: In this paper, the suppression of the coupling of a quantum bit to its environment by optimized sequences of π pulses is investigated, and it is shown that the harder the cut-off, the better an optimized pulse sequence can deal with it.
Journal ArticleDOI
Dispersion and symmetry of bound states in the shastry-sutherland model
TL;DR: Bound states made from two triplet excitations on the Shastry-Sutherland lattice based on the perturbative unitary transformation by flow equations quantitative properties like dispersions and qualitative properties like symmetries are determined.
