Quantum Paths: Navigating the Complexities of Non-Isotonic Networks

26.11.2025 by Ray Dalio

Quantum-repeater networks exhibit non-isotonic behavior where the optimal communication path shifts with network expansion; while a path $p_1 = (A, C)$ initially yields a secret-key rate of approximately 32 Hz-superior to the 59 Hz of path $p_2 = (A, B, C)$-appending a link to form $p_1 \oplus e$ results in 13 Hz, whereas $p_2 \oplus e$ yields zero utility due to error rates exceeding the BBM92 protocol’s tolerance with just three links each possessing a fidelity of 0.94.

New research explores the challenges of efficiently routing quantum information through networks where traditional pathfinding methods fall short.
