the result that the optimal error exponent for discriminating two quantum states in asymmetric hypothesis testing equals their quantum relative entropy.

In quantum information science, quantum Stein's lemma refers to the result that the optimal error exponent for discriminating two quantum states in asymmetric hypothesis testing equals their quantum relative entropy. This meaning comes from Hiai (1991) in Communications in Mathematical Physics.[1]
