通过使用任意算符(不一定是厄米算符)的广义方差,我们将量子信道的不确定性引入为量子信道的克劳斯算符的广义方差之和,并证明它满足若干期望(此处“desir”应为“desirable properties”之类的表达,原词有误)。
By use of the generalized variance for any operator (not necessarily Hermitian), we introduce the uncertainty of quantum channels as the sum of the generalized variances for the Kraus operators of quantum channels and prove that it satisfies several desirable properties. Then, we establish two trade-off relations between the uncertainty of quantum channels and the entanglement fidelity which is introduced by Schumacher (Phys. Rev. A 54: 2614, 1996) and quantifies how well the channel preserves the entanglement between the input system and the auxiliary system for purification. Finally, we illustrate the uncertainty of quantum channels through some typical examples.
