Using quantum state discrimination theory, we derive the upper bound for spoofing detection when randomly encoding two states in an electromagnetic signal. We analytic expression optimal and demonstrate that it can be saturated using a pair of coherent states. show enhancement is independent number photons; therefore, single-photon restriction unnecessary experimental demonstration. also consider squeezed signal probability approaches unity if spoofer capability limited to generation.
We employ quantum state discrimination theory to establish the ultimate limit for spoofing detection in electromagnetic signals encoded with random states. Our analysis yields an analytical expression optimal bound, which we prove can be achieved using a pair of coherent Notably, enhancement persists regardless photon number, thereby removing previous constraint single-photon sources. This breakthrough unlocks new experimental possibilities standard laser Furthermore, explore encoding...
