It is shown that the whole system can yield good squeezing, which is comparable to that produced by dispersive coupling, the numerical results which we obtained showed periodic oscillations with a maximum peaks in one of the two quadrature component with a value less than 0.5. We also showed that entanglement can be achieved by calculating the variance in quadrature component of the field operators. Our results are useful in non- degenerate parametric oscillation.<\/p>\n<p dir=\"ltr\" style=\"text-align: justify;\"><strong>Key Words: <\/strong>squeezed state, entanglement, quadrature component, variance, non-degenerate parametric.<\/p>\n<p style=\"text-align: justify;\">\u0639\u0646\u0648\u0627\u0646 \u0627\u0644\u0628\u062d\u062b<\/p>\n<p style=\"text-align: justify;\">\u062a\u0648\u0644\u064a\u062f \u0645\u0639\u0627\u0645\u0644 \u0627\u0644\u0627\u0646\u0636\u063a\u0627\u0637\u064a\u0629 \u0627\u0644\u0643\u0645\u064a\u0629 \u0648\u0627\u0644\u062a\u0634\u0627\u0628\u0643 \u0641\u064a \u062a\u062c\u0648\u064a\u0641 \u0628\u0635\u0631\u064a \u0644\u0646\u0638\u0627\u0645 \u0636\u0648\u0626\u064a \u062d\u0631\u0643\u064a<\/p>\n<p style=\"text-align: justify;\"><strong>\u0627\u0644\u0645\u0633\u062a\u062e\u0644\u0635 <\/strong><\/p>\n<p style=\"text-align: justify;\">\u0623\u064f\u062c\u0631\u064a\u062a \u0647\u0630\u0647 \u0627\u0644\u062f\u0631\u0627\u0633\u0629 \u0627\u0644\u0646\u0638\u0631\u064a\u0629 \u0644\u0646\u0638\u0627\u0645 \u0643\u0645\u064a \u0645\u0643\u0648\u0646 \u0645\u0646 \u062d\u0642\u0644 \u0643\u0647\u0631\u0648\u0645\u063a\u0646\u0627\u0637\u064a\u0633\u064a \u062b\u0646\u0627\u0626\u064a \u0627\u0644\u0646\u0633\u0642 \u0631\u064f\u0628\u0637 \u0645\u0639 \u0645\u062a\u0630\u0628\u0630\u0628 \u0645\u064a\u0643\u0627\u0646\u064a\u0643\u064a \u0623\u062d\u0627\u062f\u064a \u0627\u0644\u0646\u0633\u0642 \u062d\u0631 \u0627\u0644\u062d\u0631\u0643\u0629. \u0648\u0642\u062f \u062a\u0645 \u062a\u0648\u0636\u064a\u062d \u0623\u0646 \u0627\u0644\u0646\u0638\u0627\u0645 \u0627\u0644\u0643\u0644\u064a (\u0627\u0644\u0645\u0643\u0648\u0646 \u0645\u0646 \u0627\u0644\u062d\u0642\u0644 \u0648\u0627\u0644\u0645\u062a\u0630\u0628\u0630\u0628) \u064a\u0642\u0648\u062f \u0625\u0644\u064a \u0645\u0639\u0627\u0645\u0644 \u0627\u0646\u0636\u063a\u0627\u0637\u064a\u0629 \u0643\u0645\u064a \u064a\u0634\u0627\u0628\u0647 \u0630\u0627\u0643 \u0627\u0644\u0630\u064a \u064a\u062a\u0645 \u0627\u0644\u062d\u0635\u0648\u0644 \u0639\u0644\u064a\u0647 \u0641\u064a \u062d\u0627\u0644\u0629 \u0627\u0644\u0627\u0642\u062a\u0631\u0627\u0646 \u0627\u0644\u0645\u0628\u062f\u062f \u0644\u0644\u0637\u0627\u0642\u0629 \u0627\u0644\u0636\u0648\u0626\u064a\u0629 \u0641\u064a \u0627\u0644\u062a\u062c\u0627\u0648\u064a\u0641 \u0627\u0644\u0628\u0635\u0631\u064a\u0629. \u0648\u0642\u062f \u0623\u0634\u0627\u0631\u062a \u0627\u0644\u0646\u062a\u0627\u0626\u062c \u0627\u0644\u062a\u064a \u062a\u0645 \u0627\u0644\u062d\u0635\u0648\u0644 \u0639\u0644\u064a\u0647\u0627 \u0625\u0644\u064a \u0642\u0645\u0645 \u0644\u0644\u0631\u0633\u0645 \u0627\u0644\u0628\u064a\u0627\u0646\u064a \u0644\u0623\u062d\u062f \u0645\u0631\u0643\u0628\u0627\u062a \u0627\u0644\u0645\u062a\u063a\u064a\u0631\u0627\u062a \u0627\u0644\u062a\u0631\u0628\u064a\u0639\u064a\u0629 \u0628\u0642\u064a\u0645\u0629 \u0642\u0635\u0648\u064a \u0623\u0642\u0644 \u0645\u0646 0.5. \u0623\u064a\u0636\u0627\u064b \u0623\u0638\u0647\u0631\u062a \u0627\u0644\u0646\u062a\u0627\u0626\u062c \u0623\u0646\u0647 \u064a\u0645\u0643\u0646 \u0627\u0644\u062d\u0635\u0648\u0644 \u0639\u0644\u064a \u0627\u0644\u062a\u0634\u0627\u0628\u0643 \u0627\u0644\u0643\u0645\u064a \u0648\u0630\u0644\u0643 \u0628\u062d\u0633\u0627\u0628 \u0627\u0644\u062a\u0628\u0627\u064a\u0646 \u0644\u0645\u0631\u0643\u0628\u0627\u062a \u0627\u0644\u0645\u062a\u063a\u064a\u0631\u0627\u062a \u0627\u0644\u062a\u0631\u0628\u064a\u0639\u064a\u0629 \u0644\u0645\u0624\u062b\u0631\u0627\u062a \u0627\u0644\u062d\u0642\u0644. \u0627\u0644\u0646\u062a\u0627\u0626\u062c \u0627\u0644\u062a\u064a \u062a\u0645 \u0627\u0644\u062d\u0635\u0648\u0644 \u0639\u0644\u064a\u0647\u0627 \u0644\u0647\u0630\u0647 \u0627\u0644\u062f\u0631\u0627\u0633\u0629 \u0630\u0627\u062a \u062c\u062f\u0648\u064a \u0643\u0628\u064a\u0631\u0629 \u0641\u064a \u0627\u0644\u062a\u0637\u0628\u064a\u0642\u0627\u062a \u0627\u0644\u0625\u0644\u0643\u062a\u0631\u0648\u0646\u064a\u0629 \u0645\u062b\u0644 \u0645\u0639\u0627\u0645\u0644 \u0639\u062f\u0645 \u0627\u0644\u062a\u0641\u0633\u062e \u0627\u0644\u062d\u062f\u064a.<\/p>\n<p style=\"text-align: justify;\"><strong>\u0627\u0644\u0643\u0644\u0645\u0627\u062a \u0627\u0644\u0645\u0641\u062a\u0627\u062d\u064a\u0629: <\/strong>\u0645\u0639\u0627\u0645\u0644 \u0627\u0644\u0627\u0646\u0636\u063a\u0627\u0637\u064a\u0629 \u0627\u0644\u0643\u0645\u064a\u060c \u0627\u0644\u062a\u0634\u0627\u0628\u0643 \u0627\u0644\u0643\u0645\u064a\u060c \u0627\u0644\u0645\u0631\u0643\u0628\u0629 \u0627\u0644\u062a\u0631\u0628\u064a\u0639\u064a\u0629\u060c \u0627\u0644\u062a\u0628\u0627\u064a\u0646\u060c \u0645\u0639\u0627\u0645\u0644 \u0639\u062f\u0645 \u0627\u0644\u062a\u0641\u0633\u062e.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Taha I.
