Performance Analysis for High-Dimensional Bell-State Quantum Illumination

open access: yesPhysics
Quantum illumination (QI) is an entanglement-based protocol for improving LiDAR/radar detection of unresolved targets beyond what a classical LiDAR/radar of the same average transmitted energy can do.

Radar matched filtering using the fractional fourier transform [PDF]

open access: yes, 2010
-A matched filter is the optimal linear filter for maximizing the signal to noise ratio (SNR) in the presence of additive noise. Matched filters are commonly used in radar systems where the transmitted signal is known and may be used as a replica to be ...

Photonic based Radar: Characterization of 1x4 Mach-Zehnder Demultiplexer [PDF]

open access: yes, 2012
This work is based on a research activity which aims to implement an optical transceiver for a photonic-assisted fully–digital radar system based on optic miniaturized optical devices both for the optical generation of the radiofrequency (RF) signal and ...

Quantum Radar: State of the Art and Potential of a Newly-Born Remote Sensing Technology [PDF]

open access: yes, 2019
Quantum technology has already been introduced in many fields, like information processing and communications, and it can potentially change our approach to remote sensing in the microwave and millimeter-wave domain,

Clocks and rods in Jackiw-Teitelboim quantum gravity

open access: yesJournal of High Energy Physics, 2019
We specify bulk coordinates in Jackiw-Teitelboim (JT) gravity using a boundary-intrinsic radar definition. This allows us to study and calculate exactly diff-invariant bulk correlation functions of matter-coupled JT gravity, which are found to satisfy ...

Measurement-based quantum computing with a spin ensemble coupled to a stripline cavity [PDF]

open access: yes, 2012
Recently, a new form of quantum memory was proposed. The storage medium is an ensemble of electron spins, coupled to a stripline cavity and an ancillary readout system.

Revealing spoofing of classical radar using quantum noise

open access: yesPhysical Review Research
Electromagnetic remote sensing technologies such as radar can be misled by targets that generate spoof pulses. Typically, a would-be spoofer must make measurements to characterize a received pulse in order to design a convincing spoof pulse.
