Beyond the standard quantum limit of parametric amplification
M. Renger, S. Pogorzalek, Q. Chen +8
The low-noise amplification of weak microwave signals is crucial for countless protocols in quantum information processing. Quantum mechanics sets an ultimate lower limit of half a…
In-situ tunable nonlinearity and competing signal paths in coupled superconducting resonators
Michael Fischer, Qi-Ming Chen, Christian Besson +10
We have fabricated and studied a system of two tunable and coupled nonlinear superconducting resonators. The nonlinearity is introduced by galvanically coupled dc-SQUIDs. We simula…
Assessing three closed-loop learning algorithms by searching for high-quality quantum control pulses
Xiao-dong Yang, Christian Arenz, Istvan Pelczer +4
Designing a high-quality control is crucial for reliable quantum computation. Among the existing approaches, closed-loop leaning control is an effective choice. Its efficiency depe…
