On the role of the general non-classicality of correlations in quantum informati
内容： Entanglement is considered the most characteristic trait of quantum mechanics. Nonetheless, almost all states---including unentangled ones---of bi-and multi-partite systems exhibit some quantum...

Experimental determination of nuclear magnetic octupole moment of 137Ba+ ion
内容： We have performed precision measurements of the hyperfine intervals of the 5D3/2 and 5D5/2 manifolds of a single trapped ion, 137Ba+. We have used rf spectroscopy to measure the hyperfine inter...

Optimal design and quantum benchmarks for coherent state amplifiers
内容： We establish the ultimate quantum limits to the amplification of an unknown coherent state in the realistic setting where the expected photon number is finite. Moreover, we provide the benchmar...
