Quantum cloning with an optical fiber amplifier.
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.
متن کاملQuantum information tapping using a fiber optical parametric amplifier with noise figure improved by correlated inputs
One of the important functions in a communication network is the distribution of information. It is not a problem to accomplish this in a classical system since classical information can be copied at will. However, challenges arise in quantum system because extra quantum noise is often added when the information content of a quantum state is distributed to various users. Here, we experimentally...
متن کاملFiber optical parametric amplifier with double-pass pump configuration.
Characteristics of fiber optical parametric amplifier (FOPA) with double-pass pump configuration are experimentally investigated. The double-pass pump FOPA exhibits more than two-fold steeper gain slope in comparison to the conventional FOPA due to elongation of effective fiber length. In the L-band amplification band, a secondary idler is generated and used as the transmission signal in lieu o...

A 90-nm wideband (1500-1590nm) optical amplifier consisting of a dispersion-compensated-fiber-based Raman fiber amplifier and a semiconductor optical amplifier with gain clamping and dispersion compensation is demonstrated for wide bandwidth amplification with gain flatness as well as dispersion compensation. 10Gb/s DWDM transmission over 100km conventional single-mode fiber link with low biter...
متن کاملOptical Quantum Cloning – a Review
After a brief introduction to the quantum no-cloning theorem and its link with the linearity and causality of quantum mechanics, the concept of quantum cloning machines is sketched, following, whenever possible, the chronology of the main results. The important classes of quantum cloning machines are reviewed, in particular state-independent and state-dependent cloning machines. The 1-to-2 clon...
