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…
Two-qubit spectroscopy of spatiotemporally correlated quantum noise in superconducting qubits
Uwe von Lüpke, Félix Beaudoin, Leigh M. Norris +9
Noise that exhibits significant temporal and spatial correlations across multiple qubits can be especially harmful to both fault-tolerant quantum computation and quantum-enhanced m…
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…
Hybrid Quantum Error Correction in Qubit Architectures
Lasse Bjørn Kristensen, Morten Kjaergaard, Christian Kraglund Andersen +1
Noise and errors are inevitable parts of any practical implementation of a quantum computer. As a result, large-scale quantum computation will require ways to detect and correct er…
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…
Andreev rectifier: a nonlocal conductance signature of topological phase transitions
T. Ö. Rosdahl, A. Vuik, M. Kjaergaard +1
The proximity effect in hybrid superconductor-semiconductor structures, crucial for realizing Majorana edge modes, is complicated to control due to its dependence on many unknown m…
