Non-demolition measurement

Chinese translation: （量子）非破坏性测量

English term or phrase: Non-demolition measurement
按哥本哈根诠释,量子体系必须由经典体系来测量.在测量前,量子体系的时间演化是按照薛定厄方程进行的.在测量后,观测量的某一个本怔态被挑出来.测量把本来按薛定厄方程演化的体系破坏了.

Non-demolition measurement 是与上述矛盾的.

谢谢.

Explanation:
Quote from wiki

”The term non-demolition does not imply that the wave function fails to collapse. In fact, QND measurement is best thought of as the ideal quantum projective measurement.

A perfect QND measurement of a particle's position, in contrast, would leave the particle in its measured position. QND measurements are extremely difficult to carry out experimentally.“
