Experimental continuous variable cloning of partial quantum information
Metin Sabuncu, Gerd Leuchs, Ulrik L. Andersen
The fidelity of a quantum transformation is strongly linked with the prior partial information of the state to be transformed. We illustrate this interesting point by proposing and…

Universal optical amplification without nonlinearity
V. Josse, M. Sabuncu, N. J. Cerf +2
We propose and experimentally realize a new scheme for universal phase-insensitive optical amplification. The presented scheme relies only on linear optics and homodyne detection,…

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…
