From: High-fidelity sub-microsecond single-shot electron spin readout above 3.5 K
a Measurement of a single conductance peak (rf quadrature signal) as a function of bath temperature from 0.1 K (blue) to 3.7 K (red). Each trace is offset by 0.15 mV. b The corresponding normalised signal of the SET (maximum signal–minimum signal) from the conductance peaks in (a). The SET performance remains constant up to ~1 K and then drops quickly above 1 K. c The response time of the SET at 0.02 K and d 3.7 K by fitting to the normalised signal of the SET when applying a 500 ns square pulse. At both temperatures, we find exponential response times~50 ns.
