Phys. Rev. A 69, 062312 (2004) [6 pages]Nuclear spin qubits in a pseudospin quantum chainReceived 27 August 2003; revised 2 December 2003; published 14 June 2004 We analyze a quantum-computer design based on nuclear spin qubits in a quasi-one-dimensional chain of non-Kramers doublet atoms. We explore the use of spatial symmetry breaking to obtain control over the local dynamics of a qubit. We also study the decoherence mechanisms at the single qubit level and the interactions mediated by the magnetic media. The design can be realized in PrBr3−xFx with nuclear magnetic resonance techniques. © 2004 The American Physical Society URL:
