Quantum Enhanced Dark-Matter Search with Entangled Fock States in High-Quality Cavities
Benjamin Freiman, Xinyuan You, Andy C. Y. Li +5
We present a quantum-enhanced protocol for detecting wave-like dark matter using an array of entangled superconducting cavities initialized in an -photon Fock state. By dist…
