چکیده
Quantum illumination can utilize entangled light to detect the low-reflectivity target that is hidden in a bright thermal background. This technique applied detection of an object curved spacetime Earth, order explore how curvature affects quantum illumination. It found spatial with state transmitter outperforms coherent-state near-Earth spacetime. Moreover, either system or employed, and gravity enhance by reducing signal at receiver. Besides, our model principle be microwave thus provides, some degree, theoretical foundation for upcoming radar technologies.

Target Detection through Quantum Illumination
Classical target detection can suffer large error probabilities in noisy and lossy environments when noise photons are mistaken for signal photons reflected from an object. It has been shown theoretically that the correlation between entangled photons can be used to better discriminate between the signal photons reflected by an object and noise photons, thus reducing the probability of error [1...
متن کاملNon - Rational 2 D Quantum Gravity II . Target Space CFT
We explore the formulation of non-rational 2D quantum gravity in terms of a chiral CFT on a Riemann surface associated with the target space. The CFT in question is constructed as the collective theory for a matrix chain, which is dual to a statistical height model on dynamical triangulations. The heights are associated with the sheets of the Riemann surface, which represents an infinite branch...

متن کاملQuantum illumination versus coherent-state target detection
Abstract. Lloyd [1] proved that a large performance gain accrues from use of entanglement in single-photon target detection within a lossy, noisy environment when compared to what can be achieved with unentangled single-photon states. We show that the performance of Lloyd’s “quantum illumination” system is, at best, equal to that of a coherent-state transmitter, and may be substantially worse. ...
متن کاملEnhanced quantum state detection efficiency through quantum information processing.
We investigate theoretically and experimentally how quantum state-detection efficiency is improved by the use of quantum information processing (QIP). Experimentally, we encode the state of one 9Be(+) ion qubit with one additional ancilla qubit. By measuring both qubits, we reduce the state-detection error in the presence of noise. The deviation from the theoretically allowed reduction is due t...
