The Quantum Internet: Enhancing Classical Internet Services One Qubit at A Time

Nowadays, the classical Internet is mainly envisioned as the underlying communication infrastructure of the Quantum Internet, aimed at providing services such as signaling …

Measuring incompatibility and clustering quantum observables with a quantum switch

The existence of incompatible observables is a cornerstone of quantum mechanics and a valuable resource in quantum technologies …

Activation of thermal states by quantum SWITCH-driven thermalization and its limits

Coherently controlled thermalization via the quantum SWITCH allows to activate the state of a work medium and, hence, extract a non-zero work. However, such thermalization puts …

How Deep the Theory of Quantum Communications Goes: Superadditivity, Superactivation and Causal Activation

In the theory of quantum communications, a deeper structure has been recently unveiled, showing that the capacity does not completely characterize the channel ability to transmit information …

Work extraction from coherently activated maps via quantum switch

We characterize the impact that the application of two maps in a quantum-controlled order has on the process of work extraction …
