Information Processing with Finite Resources: Quantum Advantage and Near-term Applications

A central topic in the developing field of quantum technologies is the efficient encoding and decoding of classical information in and out of quantum systems. On the other hand, correlated quantum systems shared between distant labs could also be a resource for processing classical information. Addressing both of the above situations, we will discuss several recent developments in information processing tasks such as randomness generation, distributed computing, communication complexity, noisy channel simulation, local authentication of classical data, and distributed channel simulation. Owing to the fact that all of these tasks take into account practical concerns such as causal constraints and finite amount of resources, they entail a number of applications, which are realizable with the current state-of-the-art devices.
