Symmetry enforces entanglement at high temperatures

Amir-Reza Negari, Leonardo A. Lessa, Subhayan Sahu

Many-body quantum systems with local interactions undergo ``sudden death of entanglement" at high temperatures, whereby thermal states become classical mixtures of product states.…

Extendibility of Fermionic Gaussian States

Amir-Reza Negari, Farzin Salek

We investigate $(k_{1}, k_{2})$ -extendibility of fermionic Gaussian states, a property central to quantum correlations and approximations of separability. We show that these states are…
