• Abstract: We propose a novel dark matter detection scheme by leveraging quantum coherence across a network of multiple quantum sensors. This method effectively eliminates incoherent background noise, thereby significantly enhancing detection sensitivity. This is achieved by performing a series of basis transformation operations, allowing the coherent signal to be expressed as a combination of sensor population measurements without introducing background noise. We present a comprehensive analytical analysis and complement it with practical numerical simulations. These demonstrations reveal that signal strength is enhanced by the square of the number of sensors, while noise, primarily due to operational infidelity rather than background fluctuations, increases only linearly with the number of sensors. Our approach paves the way for next-generation dark matter searches that optimally utilize an advanced network of sensors and quantum technologies.

  We propose a novel method to significantly enhance the signal rate in qubit-based dark matter detection experiments. We show that the signal rate scales proportionally to $n_rm q2$, with $n_rm q$ being the number of sensor qubits. In the dark matter detection with a substantial number of sensor qubits, a significant increase in the signal rate can be expected.
