A self-calibrating superconducting pair-breaking detector
E. T. Mannila, V. F. Maisi, J. P. Pekola
We propose and experimentally demonstrate a self-calibrating detector of Cooper pair depairing in a superconductor based on a mesoscopic superconducting island coupled to normal me…
Coulomb Blockade Thermometry on a Wide Temperature Range
O. M. Hahtela, A. Kemppinen, J. Lehtinen +11
The Coulomb Blockade Thermometer (CBT) is a primary thermometer for cryogenic temperatures, with demonstrated operation from below 1 mK up to 60 K. Its performance as a primary the…
Real-time observation of Cooper pair splitting showing strong non-local correlations
Antti Ranni, Fredrik Brange, Elsa T. Mannila +2
Controlled generation and detection of quantum entanglement between spatially separated particles constitute an essential prerequisite both for testing the foundations of quantum m…
Optimal probabilistic work extraction beyond the free energy difference with a single-electron device
Olivier Maillet, Paolo A. Erdman, Vasco Cavina +8
We experimentally realize protocols that allow to extract work beyond the free energy difference from a single electron transistor at the single thermodynamic trajectory level. Wit…
Detecting parity effect in a superconducting device in the presence of parity switches
E. T. Mannila, V. F. Maisi, H. Q. Nguyen +2
We present a superconducting device showing a clear parity effect in the number of electrons, even when there is, on average, a single nonequilibrium quasiparticle present and the…
Determining the parameters of a random telegraph signal by digital low pass filtering
Shilpi Singh, Elsa T. Mannila, Dmitry S. Golubev +2
We propose a method to determine the switching rates of a random telegraph signal. We apply digital low pass filtering with varying bandwidth to the raw signal, evaluate the cumula…
