Abstract: We define a special class of quantum operations we call Markovian and show that it has the same spectral properties as a corresponding Markov chain. We then consider a convex combination of a quantum operation… read more here.

Abstract: Phenomena induced by the existence of entanglement, such as nonlocal correlations, exhibit characteristic properties of quantum mechanics distinguishing from classical theories. When entanglement is accompanied by classical communication, it enhances the power of quantum operations… read more here.

DOI: 10.1134/s199508021910010x
Abstract: The conventional photon subtraction and photon addition transformations, $\varrho \rightarrow t a \varrho a^†$ and $\varrho \rightarrow t a^† \varrho a$, are not valid quantum operations for any constant $t>0$ since these transformations are not… read more here.
