摘　　要：引入了叠加Trio-相干态,讨论了该量子态的完备性及其光子数统计分布和Cauchy-schwarz不等式。结果表明,该量子态存在亚泊松统计分布和违背Cauchy-Schwarz不等式等非经典特性。Superposition of trio-coherent states are introduced and the properties of the completeness relation, number distribution and Cauchy-Schwarz inequalities are studied. It is shown that these states possess sub-Poissonian number distribution and violation of Cauchy-Schwarz inequalities.

关 键 词：叠加Trio-相干态 亚泊松统计 Cauchy—Schwarz不等式
