Two-Way Communication with a Single Quantum Particle

Author(s): Flavio Del Santo and Borivoje Dakić
In this Letter we show that communication when restricted to a single information carrier (i.e., single particle) and finite speed of propagation is fundamentally limited for classical systems. On the other hand, quantum systems can surpass this limitation. We show that communication bounded to the ...
