• Abstract: Nonlocality is a key feature of quantum networks and is being studied for its potential applications in quantum communication and computing. Understanding and harnessing nonlocality in quantum networks could lead to the development of faster and more secure communication systems. All the nonclassicalities are limited to discrete variable quantum networks. We propose the first method to verify the network nonlocality of all optical quantum network consisting of two entangled states where one-way classical communication is allowed. This provides the first device-independent method to verify the quantum correlations generated from all optical continuous-variable quantum networks.

We demonstrate a general method to guarantee that certain correlations cannot be generated in a given quantum network.

  This work presents an algorithm that generates entanglement between any two directly connected nodes of a quantum network.

We show that after implementation, the probability of the walker being at all nodes other than the source and target is negligible.
