I have calculated logrithmic negativity for my biparty entangled system in a superconducting circuit. The negativity gives a sine curve where maximum value comes out to be 4 and minimum 0.5. Now, how can I know it's a substantial value or not?

  • $\begingroup$ Hi, i am using Heisenberg-lengvin equations from which i have extracted covariance matrix and from it's eigenvalue the Logarithmic negativity is extracted using conventional mathematics. $\endgroup$ Oct 30, 2022 at 16:09
