| 520 | |a Abstract Externally induced entanglement amplification in a coherently pumped correlated emission laser (CEL) with parametric amplifier and coupled to a two-mode squeezed vacuum reservoir is presented. The combination of the master equation and stochastic differential equation is employed to investigate the entanglement of the two-mode light generated by the quantum system. The resulting solutions of the correlation properties of noise forces associated with the normal ordering are used to find the mean photon number of the cross-correlated mode and separate cavity modes, quadrature fluctuations, smallest eigenvalue of the symplectic matrix, and photon number correlation function. It is found that pumping atoms from the lower energy state to excited state results in a robust entanglement that remains in its maximum strength over a wide range of the strong classical driving radiation. The introduction of the nonlinear crystal into the linear cavity, and coupling the system to the two-mode squeezed vacuum environment lead to a significant enhancement of entanglement of the cavity light. The enhanced entanglement is quantified employing logarithmic negativity, Cauchy–Schwarz inequality, and Duan et al. criteria. It has been observed that an intense light can be produced where the entanglement is strong. | ||

The combination of the master equation and stochastic differential equation is employed to investigate the entanglement of the two-mode light generated by the quantum system. The resulting solutions of the correlation properties of noise forces associated with the normal ordering are used to find the mean photon number of the cross-correlated mode and separate cavity modes, quadrature fluctuations, smallest eigenvalue of the symplectic matrix, and photon number correlation function. It is found that pumping atoms from the lower energy state to excited state results in a robust entanglement that remains in its maximum strength over a wide range of the strong classical driving radiation. The introduction of the nonlinear crystal into the linear cavity, and coupling the system to the two-mode squeezed vacuum environment lead to a significant enhancement of entanglement of the cavity light. The enhanced entanglement is quantified employing logarithmic negativity, Cauchy–Schwarz inequality, and Duan et al. criteria.

The combination of the master equation and stochastic differential equation is employed to investigate the entanglement of the two-mode light generated by the quantum system. The resulting solutions of the correlation properties of noise forces associated with the normal ordering are used to find the mean photon number of the cross-correlated mode and separate cavity modes, quadrature fluctuations, smallest eigenvalue of the symplectic matrix, and photon number correlation function. It is found that pumping atoms from the lower energy state to excited state results in a robust entanglement that remains in its maximum strength over a wide range of the strong classical driving radiation. The introduction of the nonlinear crystal into the linear cavity, and coupling the system to the two-mode squeezed vacuum environment lead to a significant enhancement of entanglement of the cavity light. The enhanced entanglement is quantified employing logarithmic negativity, Cauchy–Schwarz inequality, and Duan et al. criteria. It has been observed that an intense light can be produced where the entanglement is strong.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Parametric amplifier</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Squeezed parameter</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Quadrature squeezing</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Entanglement</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">ogarithmic negativity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cauchy–Schwarz inequality</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Brazilian journal of physics</subfield><subfield code="d">New York, NY : Springer New York, 1996</subfield><subfield code="g">50(2020), 4 vom: 02.

Enhanced CV Entanglement Quantification in a CEL with Parametric Amplifier and Coupled to Squeezed Vacuum |
| abstract |
Abstract Externally induced entanglement amplification in a coherently pumped correlated emission laser (CEL) with parametric amplifier and coupled to a two-mode squeezed vacuum reservoir is presented. The combination of the master equation and stochastic differential equation is employed to investigate the entanglement of the two-mode light generated by the quantum system. The resulting solutions of the correlation properties of noise forces associated with the normal ordering are used to find the mean photon number of the cross-correlated mode and separate cavity modes, quadrature fluctuations, smallest eigenvalue of the symplectic matrix, and photon number correlation function. It is found that pumping atoms from the lower energy state to excited state results in a robust entanglement that remains in its maximum strength over a wide range of the strong classical driving radiation. The introduction of the nonlinear crystal into the linear cavity, and coupling the system to the two-mode squeezed vacuum environment lead to a significant enhancement of entanglement of the cavity light. The enhanced entanglement is quantified employing logarithmic negativity, Cauchy–Schwarz inequality, and Duan et al. criteria. It has been observed that an intense light can be produced where the entanglement is strong. |
