Universal linear-optical quantum device: experimental implementation

Original language description

We report on a linear-optical realization of a universal quantum device working with polarization encoded quantum bits. It can serve as a two-qubit partial SWAP entangling gate. The same device can be used also for filtering symmetric and antisymmetric parts of the input two-photon state. Through a partial symmetrization, the universal asymmetric quantum cloning of single-photon polarization states can be achieved. All functions can be implemented in one setup by changing the classical parameters like the phase shift and attenuation only. For the characterization of the device, the reconstruction of the output state by full process tomography was performed.
