Unfortunately, the detection and characterization of power laws is complicated by the large fluctuations that occur in the tail of the distribution -- the pa... | [

119320251 | 0706.1038 | 2007-06-07 | Discrimination of the binary coherent signal: Gaussian-operation limit and simple non-Gaussian near-optimal receivers | We address the limit of the Gaussian operations and classical communication in the problem of quantum state discrimination. We show that the optimal Gaussian strategy for the discrimination of the binary phase shift keyed (BPSK) coherent signal is a simple homodyne detection. We also propose practical near-optimal quan... | [

The resolution is 80" (FWHM) throughout, and the typical RMS noise level is ~0.1 Jy/beam. The typical point-source detection limit is 0.7 Jy/b... | [

In particular, we have made empirical es... | [
