Continuous-variable teleportation: a new look
Paulina Marian, Tudor A. Marian
In contrast to discrete-variable teleportation, a quantum state is imperfectly transferred from a sender to a remote receiver in a continuous-variable setting. We recall the ingeni…
Entanglement of formation for an arbitrary two-mode Gaussian state
Paulina Marian, Tudor A. Marian
We write the optimal pure-state decomposition of any two-mode Gaussian state and show that its entanglement of formation coincides with the Gaussian one. This enables us to develop…
Non-Gaussian continuous-variable teleportation
Paulina Marian, Tudor A. Marian
We have recently shown that the output field in the Braunstein-Kimble protocol of teleportation is a superposition of two fields: the input one and a field created by Alice's measu…
Quantum Chernoff bound as a measure of nonclassicality for one-mode Gaussian states
Madalina Boca, Iulia Ghiu, Paulina Marian +1
We evaluate a Gaussian distance-type degree of nonclassicality for a single-mode Gaussian state of the quantum radiation field by use of the recently discovered quantum Chernoff bo…
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…
