Electrical low-frequency noise due to surface diffusion of scatterers on an ultra low noise graphene platform
Masahiro Kamada, Antti Laitinen, Weijun Zeng +5
Low-frequency noise is ubiquitous, even in high-end electronic devices. For qubits such noise results in decrease of their coherence times. Recently, it was found that adso…
A Bayesian spatiotemporal model for reconstructing climate from multiple pollen records
Lasse Holmström, Liisa Ilvonen, Heikki Seppä +1
Holocene (the last 12,000 years) temperature variation, including the transition out of the last Ice Age to a warmer climate, is reconstructed at multiple locations in southern Fin…
Superconducting transition detector in power amplification mode: a tool for cryogenic multiplexing
P. Helistö, J. Hassel, A. Luukanen +1
We demonstrate that substantial power gain can be obtained with superconducting transition detectors. We describe the properties of the detector as a power amplifier theoretically.…
Evidence of Cooper pair pumping with combined flux and voltage control
Antti O. Niskanen, Jani M. Kivioja, H. Seppa +1
We have experimentally demonstrated pumping of Cooper pairs in a single-island mesoscopic structure. The island was connected to leads through SQUID (Superconducting Quantum Interf…
The Bloch Oscillating Transistor
H. Seppä, J. Hassel
We introduce a new mesoscopic transistor, which consists of a superconducting island connected to superconducting and normal electrodes via two mesoscopic tunnel junctions. Further…
