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…
Josephson junction-embedded transmission-line resonators: from Kerr medium to in-line transmon
J. Bourassa, F. Beaudoin, Jay M. Gambetta +1
We provide a general method to find the Hamiltonian of a linear circuit in the presence of a nonlinearity. Focussing on the case of a Josephson junction embedded in a transmission-…
Ultrastrong coupling regime of cavity QED with phase-biased flux qubits
J. Bourassa, J. M. Gambetta, A. A. Abdumalikov +3
We theoretically study a circuit QED architecture based on a superconducting flux qubit directly coupled to the center conductor of a coplanar waveguide transmission-line resonator…
Collective modes of CP(3) Skyrmion crystals in quantum Hall ferromagnets
R. Cote, D. B. Boisvert, J. Bourassa +2
The two-dimensional electron gas in a bilayer quantum Hall system can sustain an interlayer coherence at filling factor nu=1 even in the absence of tunneling between the layers. Th…
Pseudospin vortex-antivortex states with interwoven spin textures in double layer quantum Hall systems
J. Bourassa, B. Roostaei, R. Cote +2
Recent experiments on strongly correlated bilayer quantum Hall systems strongly suggest that, contrary to the usual assumption, the electron spin degree of freedom is not completel…
Dynamics of electrons in the quantum Hall bubble phases
R. Cote, C. Doiron, J. Bourassa +1
In Landau levels N > 1, the ground state of the two-dimensional electron gas (2DEG) in a perpendicular magnetic field evolves from a Wigner crystal for small filling of the partial…
