Abstract
The decomposition for controlled- gate in [Phys. Rev. A, 87, 062318 (2013)] has a shallow circuit depth with no ancilla. Here we modify this decomposition to decompose -qubit Toffoli gate with only additional single-qubit gates. The circuit depth is unchanged and no ancilla is needed. We explicitly show that the circuit after decomposition can be easily constructed in present physical systems.
