For any K K -mode bosonic state ρ \rho , we can write the 𝒫 \mathcal{P} -representation ρ = ∫ d 2 ​ K 𝜶 𝒫 ( 𝜶 ) | 𝜶 ⟩ ⟨ 𝜶 | \rho=\int d^{2K}\boldsymbol{\alpha~}\mathcal{P}(\boldsymbol{\alpha})\left|\boldsymbol{\alpha}\right\rangle\left\langle\boldsymbol{\alpha}\right| , where 𝒫 ⁡ ( 𝜶 ) \mathcal{P}(\boldsymbol{\alpha}) is normalized to 1 1 and | 𝜶 ⟩ ⟨ 𝜶 | \left|\boldsymbol{\alpha}\right\rangle\left\langle\boldsymbol{\alpha}\right| is a multimode coherent state. Then, ρ \rho is called “classical” (“non-classical”) if 𝒫 ⁡ ( 𝜶 ) \mathcal{P}(\boldsymbol{\alpha}) is positive (non-positive) [ 3 ] . For ρ \rho classical, 𝒫 ⁡ ( 𝜶 ) \mathcal{P}(\boldsymbol{\alpha}) is a probability distribution (implying separability)

G > 0 G>0 is a sufficient condition for the superiority of quantum reading. G = 1 G=1 corresponds to the singular case where only quantum light can retrieve information
