Accessing the electromagnetic spectrum is the essence of modern warfare, which is
determined by the detection direction, the airframe structure, and the material. Modern …

Quantum sensing, built upon fundamental quantum phenomena like entanglement and
squeezing, is revolutionizing precision and sensitivity across diverse domains, including …

Radars use time-of-flight measurement to infer the range to a distant target from its return's
round-trip range delay. They typically transmit a high time-bandwidth product waveform and …

Quantum metrology can achieve far better precision than classical metrology, and is one of
the most important applications of quantum technologies in the real world. To attain the …

High time-bandwidth product signal and idler pulses comprised of independent identically
distributed two-mode squeezed vacuum (TMSV) states are readily produced by …

We propose a quantum-enhanced lidar system to estimate a target's radial velocity, which
employs squeezed and frequency-entangled signal and idler beams. We compare its …

The coherent transduction between microwave and optical frequencies is critical to
interconnect superconducting quantum processors over long distances. However, it is …

Entanglement is vulnerable to degradation in a noisy sensing scenario, but surprisingly, the
quantum illumination protocol has demonstrated that its advantage can survive. However …

We study quantum phase sensing with asymmetric two-mode entangled coherent states
(ECSs) in which the two local amplitudes take different values. We find the asymmetry …

Quantum repeater is an essential ingredient for quantum networks that link distant quantum
modules such as quantum computers and sensors. Motivated by distributed quantum …
