One shot entanglement assisted classical and quantum communication over noisy quantum channels: A hypothesis testing and convex split approach

Understand

Capacity of a quantum channel characterizes the limits of reliable communication through a noisy quantum channel.

• This fundamental information theoretic question is very well studied specially in the setting of many independent uses of the channel.
• An important scenario, both from practical and conceptual point of view, is when the channel can be used only once.
• This is known as the one-shot channel coding problem.
