Gaussian entanglement of symmetric two-mode Gaussian states
Paulina Marian, Tudor A. Marian
A Gaussian degree of entanglement for a symmetric two-mode Gaussian state can be defined as its distance to the set of all separable two-mode Gaussian states. The principal propert…

Optimal purifications and fidelity for displaced thermal states
Paulina Marian, Tudor A. Marian
We evaluate the Uhlmann fidelity between two one-mode displaced thermal states as the maximal probability transition between appropriate purifications of the given states. The opti…

Bures distance as a measure of entanglement for symmetric two-mode Gaussian states
Paulina Marian, Tudor A. Marian
We evaluate a Gaussian entanglement measure for a symmetric two-mode Gaussian state of the quantum electromagnetic field in terms of its Bures distance to the set of all separable…
