Random quantum noise and messy communication links can actually be used to build the connections needed for a quantum internet.
Quantum noise is usually considered the ultimate enemy because it breaks the delicate links between particles. This new method uses the superposition of communication channels to turn that noise into a tool for creating entanglement. Instead of fighting the interference, the system uses it to deterministically forge new quantum bonds. This approach shifts the focus from preserving entanglement to creating it during the transmission process. It provides a more resilient way to build global quantum networks in the presence of real-world interference.
Entanglement Generation During Distribution via Spatial Superposition Entanglement Generation

The exploitation of quantum coherence at the level of propagation represents a powerful paradigm for quantum communication networks. In this work, we show that the coherent superposition of spatially distinct communication links enables entanglement generation inherently during distribution. Specifically, separable quantum states can be deterministically transformed into entangled states, when the noisy communication links they traverse are coherently superposed. Contrary to the conventional vie
