A new study addresses the challenge of maintaining stability in quantum communication networks. Quantum networks rely on qubits for secure communication but lose connection when used repeatedly, causing instability. Researchers found that adding a specific number of connections after each communication event can keep the network functioning optimally. They determined that adding links proportional to the square root of the number of users (e.g., 1,000 links for every million users) ensures stability without overcomplicating the system. This approach balances cost and connectivity, preventing fragmentation while avoiding excessive link usage. The study suggests this method could help design resilient quantum networks capable of supporting advanced computing and secure communications. Kovács notes that this breakthrough brings us closer to realizing the full potential of quantum internet technologies.
