چکیده
In the comment [1], Zanardi and Rasetti argue that several claims in our recent letter [2] are questionable. Here we show these claims remain true. Our points are that (i) the Hamiltonian (1) in Ref. [2] describes amplitude damping as well as phase damping; (ii) the free-Hamiltonian-elimination (FHE) has feasible implementation in practice and there exists a simple FHE procedure which is designed without the knowledge of the noise parameters λ; (iii) the gate operation constructed in the letter [2] is an encoded universal operation, not an encoded controlled NOT (CNOT). (i) There are mainly two kinds of dissipation, amplitude damping and phase damping. General amplitude damping of many qubits is usually described by the following interaction Hamiltonian [3]

Radically Questioning the Principle of the Least Restrictive Alternative: A Reply to Nir Eyal; Comment on “Nudging by Shaming, Shaming by Nudging”
In his insightful editorial, Nir Eyal explores the connections between nudging and shaming. One upshot of his argument is that we should question the principle of the least restrictive alternative in public health and health policy. In this commentary, I maintain that Eyal’s argument undermines only a rather implausible version of the principle of the least restrictive alternative and I sketch ...
متن کاملEnvironmental gamma radiation: a comment (Letter to the Editor)
Editor, I read the recent publication by Toossi et al. with a great interest (1). Toossi et al. concluded that “Average gonad and bone marrow doses for North Khorasan, Boshehr and Hormozgan provinces were less than the corresponding values for normal area (2).” There are some facts on this report to be concerned. I agree that the detected levels might be high in the mentioned area, but th...
