Tripartite Genuine Non-Gaussian Entanglement in Three-Mode Spontaneous Parametric Downconversion
Andrés Agustí, C. W. Sandbo Chang, Fernando Quijandría +3
We show that the states generated by a three-mode spontaneous parametric downconversion (SPDC) interaction Hamiltonian possess tripartite entanglement of a different nature to othe…

Receiver Operating Characteristics for a Prototype Quantum Two-Mode Squeezing Radar
David Luong, C. W. Sandbo Chang, A. M. Vadiraj +3
We have built and evaluated a prototype quantum radar, which we call a quantum two-mode squeezing radar (QTMS radar), in the laboratory. It operates solely at microwave frequencies…

Quantum-Enhanced Noise Radar
C. W. Sandbo Chang, A. M. Vadiraj, J. Bourassa +2
We propose a novel protocol for quantum illumination: a quantum-enhanced noise radar. A two-mode squeezed state, which exhibits continuous-variable entanglement between so-called s…
