Quantum simulations of unphysical operations and quantum field theories in trap
Abstract: In this talk I will introduce the concept of unphysical operations and I will show how to implement them in standard quantum platforms. Unphysical operations represent a new way of interact...

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...
