Rigorous Performance Bounds for Quadratic and Nested Dynamical Decoupling
Yuhou Xia, Gotz S. Uhrig, Daniel A. Lidar
We present rigorous performance bounds for the quadratic dynamical decoupling (QDD) pulse sequence which protects a qubit from general decoherence, and for its nested generalizatio…
Rigorous Bounds for Optimal Dynamical Decoupling
Götz S. Uhrig, Daniel A. Lidar
We present rigorous performance bounds for the optimal dynamical decoupling pulse sequence protecting a quantum bit (qubit) against pure dephasing. Our bounds apply under the assum…
Generalization of short coherent control pulses: extension to arbitrary rotations
S. Pasini, G. S. Uhrig
We generalize the problem of the coherent control of small quantum systems to the case where the quantum bit (qubit) is subject to a fully general rotation. Following the ideas dev…
Exact Demonstration of Magnetization Pleateaus and First Order Dimer-Néel Phase Transitions in a Modified Shastry-Sutherland Model for SrCu(BO)
Erwin Müller-Hartmann, Rajiv R. P. Singh, Christian Knetter +1
We study a generalized Shastry-Sutherland model for the material SrCu(BO). Along a line in the parameter space, we can show rigorously that the model has a first order…
Existence of an incommensurate ground state of interacting spinless fermions in infinite dimensions
G. S. Uhrig, R. Vlaming
We focus on the ground state phase diagram of a system of spinless fermions with repulsion on a hypercubic lattice in the limit of infinite dimensions. It occurs spontaneous symmet…
