A technique for implementing a quantum circuit is provided, where the quantum circuit includes qubits and operators executed on the qubits. The operators include a sequence of π/4 Pauli rotation gates. A surface code layout includes an arrangement of the quantum circuit on a quantum chip, where the arrangement includes at least a tree with a plurality of subtrees, each rotation gate corresponding to a subtree. The technique includes iteratively generating a directed acyclic graph (DAG) of the quantum circuit, where a front layer of the DAG is a set of rotations that can be effectively implemented at each iteration. The technique includes selecting a subset of the rotations (a 'selected subset') in the front layer in which the subtrees are arranged not to intersect (“non intersecting subsets”).
