Quantum process tomography of single photon quantum channels with
controllable decoherence [PDF]
A. Shaham, H. S. EisenbergWe characterized unital quantum channels of single photon polarization qubits. The channels are composed of two birefringent crystals and wave-plates, where their decoherence properties are controlled. An experimental comparison between two different depolarizing configurations was performed using a quantum process tomography procedure. The results are with a high fidelity to the theoretical predictions.View original: http://arxiv.org/abs/1108.1543
