Charge sensitivity of the Inductive Single-Electron Transistor
Abstract
We calculate the charge sensitivity of a recently demonstrated device where the Josephson inductance of a single Cooper-pair transistor is measured. We find that the intrinsic limit to detector performance is set by oscillator quantum noise. Sensitivity better than 10-6e/Hz is possible with a high Q-value 103, or using a SQUID amplifier. The model is compared to experiment, where charge sensitivity 3 × 10-5e/Hz and bandwidth 100 MHz are achieved.
