Additive Invariants on Quantum Channels and Applications to Regularized Minimum Entropy *
نویسنده
چکیده
We introduce two additive invariants of output quantum channels. If the value of one these invariants is less than 1 then the logarithm of the inverse of its value is a positive lower bound for the regularized minimum entropy of an output quantum channel. We give a few examples in which one of these invariants is less than 1.

We introduce two additive invariants of output quantum channels. If the value of one these invariants is less than 1 then the logarithm of the inverse of its value is a positive lower bound for the regularized minimum entropy of an output quantum channel. We give a few examples in which one of these invariants is less than 1. We also study the special cases where the above both invariants are e...
متن کاملThe minimum Renyi entropy output of a quantum channel is locally additive
We show that the minimum Renyi entropy output of a quantum channel is locally additive for Renyi parameter α > 1. While our work extends the results of [11] (in which local additivity was proven for α = 1), it is based on several new techniques that incorporate the multiplicative nature of `p-norms, in contrast to the additivity property of the von-Neumann entropy. Our results demonstrate that ...
متن کاملAdditivity of the Classical Capacity of Entanglement-Breaking Quantum Channels
Abstract We show that for the tensor product of an entanglement-breaking quantum channel with an arbitrary quantum channel, both the minimum entropy of an output of the channel and the Holevo-Schumacher-Westmoreland capacity are additive. In addition, for the tensor product of two arbitrary quantum channels, we give a bound involving entanglement of formation for the amount of subadditivity (fo...
متن کاملEmerging from Noisy Quantum Channels
In this paper, we consider the minimal entropy of two-qubit states transmitted through two uses of a noisy quantum channel, which is modeled by the action of a completely positive trace-preserving (or stochastic) map. We provide strong support for the conjecture that this minimal entropy is additive, namely that the minimum entropy can be achieved when product states are transmitted. Explicitly...
