Sequential Probability Ratio Test for the detection of a single electron spin in the OSCAR setup
arXiv:quant-ph/0402181
Abstract
The MRFM device is a powerful setup for manipulating single electron spin in resonance in a magnetic field. However, the real time observation of a resonating spin is still an issue because of the very low SNR of the output signal. This paper investigates the usability and the efficiency of sequential detection schemes (the Sequential Probability Ratio Test) to decrease the required integration time, in comparison to standard fixed time detection schemes.
