Leggett-Garg tests of macro-realism for multi-particle systems including double-well Bose-Einstein condensates
L. Rosales-Zárate, B. Opanchuk, Q. Y. He +1
We construct quantifiable generalisations of Leggett-Garg tests for macro/ mesoscopic realism and noninvasive measurability that apply when not all outcomes of measurement can be i…
Fulde-Ferrell-Larkin-Ovchinnikov pairing states between - and -orbital fermions
Shu-Yang Wang, Jing-Wei Jiang, Yue-Ran Shi +2
We study pairing states in an largely imbalanced two-component Fermi gas loaded in an anisotropic two-dimensional optical lattice, where the spin up and spin down fermions filled t…
Correlation based entanglement criteria for bipartite systems
Yumang Jing, Qiongyi He, Tim Byrnes
We introduce a class of inequalities based on low order correlations of operators to detect entanglement in bipartite systems. The operators may either be Hermitian or non-Hermitia…
Spin-Orbit Coupling Induced Spin Squeezing in Three-Component Bose Gases
X. Y. Huang, F. X. Sun, W. Zhang +2
We observe spin squeezing in three-component Bose gases where all three hyperfine states are coupled by synthetic spin-orbit coupling. This phenomenon is a direct consequence of sp…
Multipartite Gaussian steering: monogamy constraints and quantum cryptography applications
Yu Xiang, Ioannis Kogias, Gerardo Adesso +1
We derive laws for the distribution of quantum steering among different parties in multipartite Gaussian states under Gaussian measurements. We prove that a monogamy relation akin…
Unconditional security of entanglement-based continuous-variable quantum secret sharing
Ioannis Kogias, Yu Xiang, Qiongyi He +1
The need for secrecy and security is essential in communication. Secret sharing is a conventional protocol to distribute a secret message to a group of parties, who cannot access i…
