Correlation Measurement of Squeezed Light
Leonid A. Krivitsky, Ulrik L. Andersen, Ruifang Dong +3
We study the implementation of a correlation measurement technique for the characterization of squeezed light which is nearly free of electronic noise. With two different sources o…
Feasibility of free space quantum key distribution with coherent polarization states
D. Elser, T. Bartley, B. Heim +3
We demonstrate for the first time the feasibility of free space quantum key distribution with continuous variables under real atmospheric conditions. More specifically, we transmit…
Demonstration of near-Optimal Discrimination of Optical Coherent States
C. Wittmann, M. Takeoka, K. N. Cassemiro +3
The optimal discrimination of non-orthogonal quantum states with minimum error probability is a fundamental task in quantum measurement theory as well as an important primitive in…
Electronic noise-free measurements of squeezed light
Leonid A. Krivitsky, Ulrik L. Andersen, Ruifang Dong +3
We study the implementation of a correlation measurement technique for the characterization of squeezed light. We show that the sign of the covariance coefficient revealed from the…
Quantum Filtering of Optical Coherent States
C. Wittmann, D. Elser, U. L. Andersen +3
We propose and experimentally demonstrate non-destructive and noiseless removal (filtering) of vacuum states from an arbitrary set of coherent states of continuous variable systems…
Quantum process tomography and Linblad estimation of a solid state qubit
M. Howard, J. Twamley, C. Wittmann +3
We present an example of quantum process tomography (QPT) performed on a single solid state qubit. The qubit used is two energy levels of the triplet state in the Nitrogen-Vacancy…
