Quantum illumination networks [PDF]
Communications PhysicsQuantum illumination is an entanglement-based target detection protocol that provides quantum advantages despite entanglement-breaking noise. However, the advantage of traditional quantum illumination protocols is limited to impractical scenarios with ...

Imaging through noise with quantum illumination. [PDF]
Sci Adv, 2020 The contrast of an image can be degraded by the presence of background light and sensor noise. To overcome this degradation, quantum illumination protocols have been theorized that exploit the spatial correlations between photon pairs.

Microwave Quantum Illumination [PDF]
Physical Review Letters, 2015 Quantum illumination is a quantum-optical sensing technique in which an entangled source is exploited to improve the detection of a low-reflectivity object that is immersed in a bright thermal background.

How discord underlies the noise resilience of quantum illumination [PDF]
New Journal of Physics, 2016 The benefits of entanglement can outlast entanglement itself. In quantum illumination, entanglement is employed to better detect reflecting objects in environments so noisy that all entanglement is destroyed.

Secure communication via quantum illumination [PDF]
Quantum Information Processing, 2016 In the quantum illumination protocol for secure communication, Alice prepares entangled signal and idler beams via spontaneous parametric downconversion. She sends the signal beam to Bob, while retaining the idler.

Feedback-enabled Microwave Quantum Illumination [PDF]
Quantum Science and Technology, 2022 A simple feedback scheme can be used to operate efficiently a microwave-quantum-illumination device based on electro-optomechanical systems also in regimes in which excess dissipation would, otherwise, prevent to outperform the optimal classical ...

Experimental Realization of Quantum Illumination [PDF]
Physical Review Letters, 2013 We present the first experimental realization of the quantum illumination protocol proposed by Lloyd [ Science 321 1463 (2008)] and S. Tan et al. [ Phys. Rev. Lett.

Quantum illumination with a generic Gaussian source [PDF]
Physical Review Research, 2020 With the aim to loosen the entanglement requirements of quantum illumination, we study the performance of a family of Gaussian states at the transmitter, combined with an optimal and joint quantum measurement at the receiver.

Quantum information to the home [PDF]
, 2011 Information encoded on individual quanta will play an important role in our future lives, much as classically encoded digital information does today. Combining quantum information carried by single photons with classical signals encoded on strong laser ...
