Quantum Cloning with an Optical Fiber Amplifier

Publication date2002

It has been shown theoretically that a light amplifier working on the physical principle of stimulated emission should achieve optimal quantum cloning of the polarization state of light. We demonstrate close-to-optimal universal quantum cloning of polarization in a standard fiber amplifier for telecom wavelengths. For cloning 1→2 we find a fidelity of 0.82, the optimal value being 5/6=0.83.
