Authors: Rosario, Pedro; Santos, Alan c. Journal: EPL Publication date: 2025/01/01 DOI: 10.1209/0295-5075/ad8f5e Abstract: - Quantum obesity (QO) is a novel function introduced to quantify quantum correlations that go beyond traditional measures like entanglement, while also functioning as an entanglement witness. One of the key strengths of QO lies in its analyticity for arbitrary states [...]
Authors: Berrocal, J.; Hernandez, A.; Porras, D.; Rodriguez, D. Journal: PHYSICAL REVIEW A Publication date: 2025/01/01 DOI: 10.1103/PhysRevA.110.063107 Abstract: In this paper we measure all the motional-mode frequencies (common and stretch) of a balanced and an unbalanced two-ion Coulomb crystal in a 7-tesla Penning trap using an electric-dipole transition in 40Ca+. The three common modes [...]
