摘要
Abstract
The high-order squeezing properties of pure superposition states |mR〉=am|m〉+βn|n〉(n>m,n≠m+1) are studied in this paper. The result shows that there is no the high-order squeezing defined by Hong and Mandel in the superposition saute when n-m=2l+1 (l≠0), but, maybe, only 2N(N≥1)-order squeezing is there in the state when n-m=2l(l≠0). A criterion determining a high-order squeezing is given.
