Characterizing and optimizing qubit coherence based on SQUID geometry
Jochen Braumüller, Leon Ding, Antti Vepsäläinen +12
The dominant source of decoherence in contemporary frequency-tunable superconducting qubits is 1/ flux noise. To understand its origin and find ways to minimize its impact, we s…

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…

Superconducting Qubits: Current State of Play
Morten Kjaergaard, Mollie E. Schwartz, Jochen Braumüller +4
Superconducting qubits are leading candidates in the race to build a quantum computer capable of realizing computations beyond the reach of modern supercomputers. The superconducti…
