In: Physical Review A Jg. 75(2007), 042314.http://hdl.handle.net/2003/25401http://dx.doi.org/10.17877/DE290R-3035Minimizing the effect of decoherence on a quantum register must be a central part of any strategy to realize scalable quantum-information processing. Apart from the strength of the coupling to the environment, the decoherence rate is determined by the system level structure and by the spectral composition of the noise trace that the environment generates. Here, we discuss a relatively simple model that allows us to study these different effects quantitatively in detail. We evaluate the effect that the perturbation has on a nuclear magnetic resonance system while it performs a Grover search algorithm.en©2007 The American Physical Society530Text10.1103/PhysRevA.75.042314http://dx.doi.org/10.1103/PhysRevA.75.042314
