Entanglement replication in driven-dissipative many body systems

TL;DR

This paper demonstrates that local nonclassical driving of many-body systems can replicate entanglement across large distances in steady state, enabling scalable quantum communication.

Contribution

It introduces a novel mechanism for scale-free entanglement replication in driven-dissipative many-body systems using a common entangled field.

Findings

Entanglement is replicated in an arbitrarily large series of inter-array pairs.

Long-distance entanglement distribution is achieved in steady state.

The mechanism has implications for quantum communication networks.

Abstract

We study the dissipative dynamics of two independent arrays of many-body systems, locally driven by a common entangled field. We show that in the steady state the entanglement of the driving field is reproduced in an arbitrarily large series of inter-array entangled pairs over all distances. Local nonclassical driving thus realizes a scale-free entanglement replication and long-distance entanglement distribution mechanism that has immediate bearing on the implementation of quantum communication networks.
