Communication Enhancement Through Quantum Coherent Control of $N$ Channels in an Indefinite Causal-order Scenario

Understand

In quantum Shannon theory, transmission of information is enhanced by quantum features.

• Up to very recently, the trajectories of transmission remained fully classical.
• Recently, a new paradigm was proposed by playing quantum tricks on two completely depolarizing quantum channels i.e.
• using coherent control in space or time of the two quantum channels.
