Strengthened Monotonicity of Relative Entropy via Pinched Petz Recovery Map
The quantum relative entropy between two states satisfies a monotonicity property meaning that applying the same quantum channel to both states can never increase their relative entropy. It is known that this inequality is only tight when there is a recovery map that exactly reverses the effects of...
