Engineering the Level Structure of a Giant Artificial Atom in Waveguide Quantum Electrodynamics
A. M. Vadiraj, Andreas Ask, T. G. McConkey +4
Engineering light-matter interactions at the quantum level has been central to the pursuit of quantum optics for decades. Traditionally, this has been done by coupling emitters, ty…
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…
Lattice gauge fields via modulation in circuit QED: The bosonic Creutz ladder
Hadiseh Alaeian, Chung Wai Sandbo Chang, Mehran Vahdani Moghaddam +3
In this work we propose two protocols to make an effective gauge potential for microwave photons in circuit QED. The schemes consist of coupled transmons whose flux are harmonicall…
