Abstract
Sense+compute (S+C) quantum-state carriers (QSCs), e.g., rubidium atoms, can be used provide more scalable quantum sensor systems. Multiple S+C QSCs can capture sensor data. The sensor data can then be transformed in the quantum domain according to a quantum tomographic protocol. The transformed data can be measured to provide a respective classical domain measurement. The sensing, transformation, and measurement can be repeated to provide a set of measurements (corresponding to different transformations) that can be combined according to the quantum tomography protocol to generate a model of the original quantum state. Estimation error associated with the model can be scaled down at a rate corresponding more closely to increases in the number N of QSCs than √{square root over (N)}, even in the presence of noise.
