Universal non-adiabatic control of small-gap superconducting qubits
Daniel L. Campbell, Yun-Pil Shim, Bharath Kannan +7
Resonant transverse driving of a two-level system as viewed in the rotating frame couples two degenerate states at the Rabi frequency, an amazing equivalence that emerges in quantu…
Generating Spatially Entangled Itinerant Photons with Waveguide Quantum Electrodynamics
Bharath Kannan, Daniel Campbell, Francisca Vasconcelos +10
Realizing a fully connected network of quantum processors requires the ability to distribute quantum entanglement. For distant processing nodes, this can be achieved by generating,…
Waveguide Quantum Electrodynamics with Giant Superconducting Artificial Atoms
Bharath Kannan, Max Ruckriegel, Daniel Campbell +14
Models of light-matter interactions typically invoke the dipole approximation, within which atoms are treated as point-like objects when compared to the wavelength of the electroma…
A tunable coupling scheme for implementing high-fidelity two-qubit gates
Fei Yan, Philip Krantz, Youngkyu Sung +6
The prospect of computational hardware with quantum advantage relies critically on the quality of quantum gate operations. Imperfect two-qubit gates is a major bottleneck for achie…
