By using the theory of multimode squeezed states,the properties of unequal-power Nj-th power sum-squeezing of multimode superposition state light field |ψ(α)q with the superposition of two quantum states in medium was studied.It was found that when the sum of the squeezing power of each mode was even number,the multimode superposition state light field |ψ(α)q was always in Nj minimum uncertainty state;when the sum of the squeezing orders of each mode was odd number,under some conditions,the multimode superposition state light field |ψ(α)q could also present Nj-th power sum-squeezing that changed periodically in medium.

Aim The properties of even-power Y-squeezing in the multimode superposition state light field |Ψ(ab)〉q with the superposition of distinct two quantum states are studied in detail.Methods Account analytical induction and summarization by utilizing the theory of multimode squeezed states.Results The properties of even-power Y-squeezing is found in the multimode superposition state light field |Ψ(ab)〉q.Conclusion The squeezed power number Nj is an even number,under some certain conditions the state |Ψ(ab)〉q can display the effects of even-power Y-squeezing.
