摘要：
Godsil proved that there is no quantum perfect state transfer (between vertex states) on bounded infinite graphs. We show however there exists quantum perfect state transfer in graphs with tails. The main argument used is a decoupling theorem for eventually-free Jacobi matrices (due to Golinskii). Our results rehabilitate the notion of a dark subspace which had been so far viewed in an unflattering light. (c) 2025 Elsevier Inc.
