Query: Implementations of more general solid-state (SWAP)$^{1/m}$ and
  controlled-(swap)$^{1/m}$ gates   Universal quantum gates are the core elements in quantum information
processing. We design two schemes to realize more general (SWAP)$^{1/m}$ and
controlled--(swap)$^{1/m}$ gates (for integer $m\geq1$) by directing flying
single photons to solid--state quantum dots. The parameter $m$ is easily
controlled by adjusting two quarter--wave plates and one half--wave plate.
Additional computational qubits are not required to construct the two gates.
Evaluations of the gates indicate that our proposals are feasible with current
experimental technology.
