Experimental demonstration of coherent state estimation with minimal disturbance
Ulrik L. Andersen, Metin Sabuncu, Radim Filip +1
We investigate the optimal tradeoff between information gained about an unknown coherent state and the state disturbance caused by the measurement process. We propose several optic…
Experimental purification of coherent states
Ulrik L. Andersen, Radim Filip, Jaromir Fiurasek +2
We propose a scheme for optimal Gaussian purification of coherent states from several imperfect copies. The proposal is experimentally demonstrated for the case of two copies of a…
Unconditional quantum cloning of coherent states with linear optics
Ulrik L. Andersen, Vincent Josse, Gerd Leuchs
A scheme for optimal Gaussian cloning of optical coherent states is proposed and experimentally demonstrated. Its optical realization is based entirely on simple linear optical ele…
