Experimental determination of nuclear magnetic octupole moment of 137Ba+ ion
Abstract: 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 i...

Optimal design and quantum benchmarks for coherent state amplifiers
Abstract: 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 benc...

Reliable quantum cloning at the Heisenberg limit
Abstract: No process in nature can perfectly copy an arbitrary quantum state. But is it possible to engineer processes that replicate quantum states with vanishingly small error? We devised a probabi...
