Dynamics and control of a quasi-one-dimensional spin system

P Cappellaro, C Ramanathan, DG Cory - Physical Review A—Atomic …, 2007 - APS

a test bed for multibody dynamics and quantum-information processing. This system is a …

Reduced decoherence in large quantum registers

HG Krojanski, D Suter - Physical review letters, 2006 - APS
Among the biggest obstacles for building larger (and thus more powerful) quantum-
information processors is decoherence, the decay of quantum-information by the coupling …

Decoherence in large quantum registers under variable interaction with the environment

M Lovrić, HG Krojanski, D Suter - Physical Review A—Atomic, Molecular, and …, 2007 - APS
Effective quantum-information processing requires coherent control of large numbers of
qubits on a time scale that is short compared to the decoherence time of the system. It is …

Decoherence in large NMR quantum registers

HG Krojanski, D Suter - Physical Review A—Atomic, Molecular, and Optical …, 2006 - APS
Decoherence causes the decay of the quantum information that is stored in highly correlated
states during quantum computation. It is thus a limiting factor for all implementations of a …

Numerical analysis of relaxation times of multiple quantum coherences in the system with a large number of spins
