We propose a novel approach for precision measurement utilizing an ensemble of probabilistic bits (p-bits). This method leverages the inherent fluctuations of p-bits to achieve high sensitivity in various applications, including magnetic field sensing, temperature monitoring and timekeeping. The sensitivity scales proportionally to the square root of the total number of p-bits, enabling unprecedented accuracy with large ensembles. Furthermore, the robustness of this method against device imperfections and non-uniformity enhances its practicality and scalability. This work paves the way for a new paradigm in precision measurement, offering a cost-effective and versatile alternative to traditional methods.
