Dynamics of the entropic uncertainty as a function of time t in the single-sided dissipative channel by homodyne-based feedback control F 1 = λ σ x . (a) Channel A is a dissipative channel with γ A = 1 , channel B is an ideal noise free channel. (b) Channel A is an ideal noise free channel, channel B is a dissipative channel with γ B = 1 .
