Quantum Capacities of Bosonic Channels [PDF]
We investigate the capacity of bosonic quantum channels for the transmission of quantum information. Achievable rates are determined from measurable moments of the channel by showing that every channel can asymptotically simulate a Gaussian channel which

Classical -Quantum Multiple Access Channel with Secrecy Constraint: One-shot Rate Region
In this paper, we aim to study a -user quantum multiple access wiretap channel with an arbitrary number of wiretappers under one-shot setting. In this regard, we first introduce the general quantum multiple access wiretap channel and the simplified ...

Enhanced Estimation of a Noisy Quantum Channel Using Entanglement [PDF]
We discuss the estimation of channel parameters for a noisy quantum channel - the so-called Pauli channel - using finite resources. It turns out that prior entanglement considerably enhances the fidelity of the estimation when we compare it to an ...

Quantum circuit design for accurate simulation of qudit channels
We construct a classical algorithm that designs quantum circuits for algorithmic quantum simulation of arbitrary qudit channels on fault-tolerant quantum computers within a pre-specified error tolerance with respect to diamond-norm distance.

Entanglement generation with a quantum channel and a shared state [PDF]
We introduce a new protocol, the channel-state coding protocol, to quantum Shannon theory. This protocol generates entanglement between a sender and receiver by coding for a noisy quantum channel with the aid of a noisy shared state.

The Structure and Quantum Capacity of a Partially Degradable Quantum Channel
The quantum capacity of degradable quantum channels has been proven to be additive. On the other hand, there is no general rule for the behavior of quantum capacity for antidegradable quantum channels.

Dynamic model of an optical channel for a quantum key distribution system in MATLAB Simulink
Relevance. Improving post-processing algorithms for key information transmitted via optical channels, as well as planning the architecture of quantum networks require realistic data.
