Publisher's Note: Decoherence and gate performance of coupled solid-state qubits [Phys. Rev. A 67, 042319 (2003)]

This article was published 23 April 2003 missing a few modifications previously indicated on the page proofs. In Eq. (15), the last term in the equation should read ±ω. On page 042319-3, in the third paragraph in the right-hand column, the first two sentences should read 'In general, the eigenstates are a superposition of singlet/triplet states. Figure 2 shows how singlet/triplet states combine into eigenstates for different qubit parameters'. These errors were rectified as of 28 April 2003. The article is correct in the printed journal
