Trade-off capacities of the quantum Hadamard channels [PDF]
, 2010 Coding theorems in quantum Shannon theory express the ultimate rates at which a sender can transmit information over a noisy quantum channel. More often than not, the known formulas expressing these transmission rates are intractable, requiring an ...

Quantifying Quantumness of Channels Without Entanglement
PRX Quantum, 2022 Quantum channels breaking entanglement, incompatibility, or nonlocality are defined as such because they are not useful for entanglement-based, one-sided device-independent, or device-independent quantum-information processing, respectively.

Solving Quantum Channel Discrimination Problem With Quantum Networks and Quantum Neural Networks
IEEE Access, 2019 Distinguishing one quantum channel from another becomes a next natural question following the advent of quantum state discrimination. Here, we address the problem of quantum channel discrimination with the separable states and the entangled states input.

Maximal Privacy Without Coherence [PDF]
, 2014 Privacy lies at the fundament of quantum mechanics. A coherently transmitted quantum state is inherently private. Remarkably, coherent quantum communication is not a prerequisite for privacy: there are quantum channels that are too noisy to transmit any ...

The Structure and Quantum Capacity of a Partially Degradable Quantum Channel
IEEE Access, 2014 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.

Comparison of Quantum Channels by Superchannels [PDF]
IEEE Transactions on Information Theory, 2018 We extend the definition of the conditional min-entropy from bipartite quantum states to bipartite quantum channels. We show that many of the properties of the conditional min-entropy carry over to the extended version, including an operational ...
