Abstract
Quantum non-demolition (QND) variables are generalized to the nonlocal ones by proposing QND measurement networks of Bell states and multi-partite GHZ states, which means that we can generate and measure them without any dest ruction. One of its prospective applications in the quantum authentication (QA) system of the quantum security automatic Teller machine (QSATM) which is much more reliable than the classical ones is also presented.
