I mangaged to include the wrong example, sorry.
Here's the correct one:

\documentclass{article}
\usepackage[line,dvips,matrix,arrow,frame,curve]{xy}

\begin{document}
\newcommand{\cistate}[1]{*+++[o][F]\txt{#1}}

\xymatrix{%
\cistate{AAAA} \ar@/_1pc/[r]_{a} &
\cistate{BBBB} \ar@/_1pc/[l]_{b}\\
}
\end{document}
