What is it about?
Unlike classical sensor networks, quantum sensor networks have a unique step: initializing the sensor network in a particular quantum state. A popular initial state is the uniform superposition state, but is it the optimal initial state? The answer is no. This paper shows the optimal initial state for detector sensors in quantum sensor networks is a Dicke state.

Why is it important?
Different initial states can affect the performance of a quantum sensor network. So we aim to discover the optimal initial state to let the quantum sensor network achieve its best performance.
Perspectives
This paper has both interesting theories and numerical simulation results. Actually, it was the simulation results that inspired our theories, and we have successfully found a pathway to prove them.
