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…
Quantum Electric Circuits Analogous to Ballistic Conductors
Daniela Dragoman
The conductance steps in a constricted two-dimensional electron gas and the minimum conductivity in graphene are related to a new uncertainty relation between electric charge and c…
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…
Metamaterials for Ballistic Electrons
Daniela Dragoman, Mircea Dragoman
The paper presents a metamaterial for ballistic electrons, which consists of a quantum barrier formed in a semiconductor with negative effective electron mass. This barrier is the…
