Abstract

The result that Lynch and Mavromatis [Phys. Rev. A 52, 55 (1995)] obtained by Puri's definition of squeezing has no relation to Hong and Mandel"s higher-order squeezing [Phys. Rev. Lett. 54, 323 (1985)]. We also point out that, for an electromagnetic field, the nonclassicality of the squeezed state defined according to Puri's general uncertainty relation is not preserved.

The paper of Yunjie, Kezhu, and Xianghe [Phys. Rev. A 55, 1548 (1997)] points out an error in the conclusions of Lynch and Mavromatis [Phys. Rev. A 52, 55 (1995)]. In the present paper it is shown how, with the appropriate modifications, the results of Lynch and Mavromatis may still be used.

Reply to ‘‘Jackiw state and higher-order squeezing of the electromagnetic field’’

Cao Hong, L. Mandeļ

In response to the preceding Comment by Lynch, it is pointed out that squeezing does not require that the uncertainty product be a minimum, but for higher-order squeezing two field components that differ in phase by less than \ensuremath{\pi}/2 may be more appropriate as canonical conjugates than the two quadratures.

Puri’s criterion and higher-order squeezing

Robert Lynch, Harry A. Mavromatis

Recently, Puri revisited the usual uncertainty relation arguments. Utilizing a well-known and sharpened version of the uncertainty relation, he has proposed an alternative squeezing criterion for the case of noncanonical operators. We investigated this in the hope that Puri's proposal might allow one to define a higher-order squeezing criterion that would avoid an anomaly found with the standard Hong-Mandel (HM) scheme, i.e., the possibility of simultaneous-quadrature squeezing. However, it is found that higher-order squeezing based on Puri's squeezing criterion has what one might judge to be an even worse and unphysical defect than the HM scheme, in that even at the squeezing ``trigger level,'' squeezing in one quadrature is necessarily accompanied by considerable antisqueezing in the other quadrature.
