We present an algorithm for solving bivariate polynomial systems with coefficients in $\mathbb{Q}$ with essentially optimal bit complexity. The core of the algorithm is a classical Newton iteration procedure. New ingredients are needed, though, such as Kedlaya-Umans' modular composition algorithm and deflation techniques due to Lecerf.

Joint work with Esmaeil Mehrabi.
