description Quantum sensors have the characteristics of high sensitivity, high accuracy and strong stability and have been used in many fields. However, though many applications require arrays of multiple quantum sensors, most of the current applications still focus on single quantum sensors. Entangled multi-quantum sensor arrays has the advantage of high precision, high accuracy, and better utilization of entanglement. In this paper, we propose an entangled photonic quantum sensor network with a radio frequency spectral range with the sensitivity and accuracy of sensors even beyond the standard quantum limit (SQL). Based on this model, we derived the variance model of the sensor array and analyzed the optimize parameter settings the sensor array and verified it by simulation. Entangled sensor network performs much better than classical sensor structure, but entanglement also increase the complexity for probe state setting.
