We propose a scheme for realizing the scalable quantum computation based on nonidentical quantum dots trapped in a single-mode waveguide. In this system, the quantum dots simultaneously interact with a large detuned waveguide and classical light fields. During the process, neither the waveguide mode nor the quantum dots are excited, while the sub-system composed of any two quantum dots can acquire phases conditional upon the states of these two quantum dots and the certain detunings between the waveguide mode and corresponding external light fields. Therefore, it can be used to realize selective quantum phase gates, graph states, N-qubit controlled phase π gates, and cluster states.
