Characterizing cryogenic amplifiers with a matched temperature-variable noise source
Slawomir Simbierowicz, Visa Vesterinen, Joshua Milem +7
We present a cryogenic microwave noise source with a characteristic impedance of 50 , which can be installed in a coaxial line of a cryostat. The bath temperature of the noise s…

Unconventional field-effect transistor composed of electrons floating on liquid helium
K. Nasyedkin, H. Byeon, L. Zhang +5
We report on an unconventional field effect transistor composed of electrons floating above the surface of superfluid helium. With this device unique transport regime…

Single-shot readout of hole spins in Ge
Lada Vukušić, Josip Kukučka, Hannes Watzinger +3
The strong atomistic spin orbit coupling of holes makes single-shot spin readout measurements difficult because it reduces the spin lifetimes. By integrating the charge sensor into…
