Error Compensation for Radome Measurements
Geometries for measuring radome characteristics can usually be split into two categories. The first category always has the antenna inside the radome pointing along the range axis. The second category has the antenna maintaining a fixed relationship with respect to the radome during each scan of data. A facility can generally be designed to minimize measurement errors in one of the two geometri...
متن کاملError Models for Long-Distance Qubit Teleportation
A recent proposal for realizing long-distance, highfidelity qubit teleportation is reviewed. This quantum communication architecture relies on an ultrabright source of polarizationentangled photons plus a pair of trapped-atom quantum memories, and it is compatible with long-distance transmission over standard telecommunication fiber. Models are developed for assessing the effects of amplitude, ...
متن کاملA Wavelet-based Spoofing Error Compensation Technique for Single Frequency GPS Stationary Receiver
Spoofing could pose a major threat to Global Positioning System (GPS) navigation, so the GPS users have to gain an in-depth understanding of GPS spoofing. Since spoofing attack can influence position results, spoof compensation is possible through reducing position deviations. In this paper, a novel processing technique is proposed and the wavelet transform is used to eliminate the impact of sp...
متن کاملHigh error-rate quantum key distribution for long-distance communication
In the original BB84 protocol by Bennett and Brassard, an eavesdropper is detected because his attempts to intercept information result in a bit transmission error rate of at least 25%. Here we design an alternative quantum key distribution protocol where Alice and Bob use two mutually unbiased bases with one of them encoding a “0” and the other encoding a “1.” For higher-dimensional photon sta...
متن کاملA Photoelectric Densitometer for Use with Suspensions
A device for quickly and accurately measuring the population density of a suspension of microorganisms, permitting the preparation of yeast suspensions of known density to within 1 per cent error, was constructed with two Visitron photoelectric cells, a single light of high intensity and a good Wheatstone bridge for balancing the currents from the two photoelectric cells. A large Pyrex milk cul...
