讨论了与孤立零模存在有关的影响。有人认为，这个系统的量子化必然包含高度扩展的量子态，通过与量子系统相互作用来填充和减少这样的状态会导致长距离的类似传送的过程。也导致费米子宇称对称性的自发破坏。一个准现实的模型组成的量子线嵌入在p波超导体被讨论作为一个明确的例子，一个孤立的马约拉纳零模式的物理系统。C
Efiects associated with the existence of isolated zero modes of Majorana fermions are discussed. It is argued that the quantization of this system necessarily contains highly extended quantum states and that populating and depopulating such states by interacting with the quantum system leads to long-ranged teleportation-like processes. Also leads to spontaneous violation of fermion parity symmetry. A quasi-realistic model consisting of a quantum wire embedded in a p-wave superconductor is discussed as an explicit example of a physical system with an isolated Majorana zero mode. c
