- Title: Operating Fiber Networks in the Quantum Limit
- Authors: Janis N\"otzel and Matteo Rosati
- Abstract summary: We show that a use of optimal quantum receivers allows an estimated $55%$ decrease in energy consumption of all-optical amplifiers in network configurations that are typical today.
We find that quantum receiver technology allows for a logarithmic scaling of the system capacity with the baud-rate, while Shannon-type systems are limited by the transmit power.

- Abstract: We consider all-optical network evolution from a quantum perspective. We show
that a use of optimal quantum receivers allows an estimated $55\%$ decrease in
energy consumption of all-optical amplifiers in network configurations that are
typical today. We then compare data transmission capacities of quantum
receivers with today's technology operating within the boundaries set by
Shannon. We find that quantum receiver technology allows for a logarithmic
scaling of the system capacity with the baud-rate, while Shannon-type systems
are limited by the transmit power. Thus a natural quantum limit of classical
data transmission emerges. Based on the above findings we argue for a new
approach to optical communication network design, wherein in-line amplifiers
are replaced by novel fiber supporting high spectral bandwidth to allow for
noiseless data transmission in the quantum limit.
