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...

Interacting fermions and bosons with trapped ions
Abstract: In this talk we will propose a method of simulating efficiently many-body interacting fermion and fermion-boson lattice models in trapped ions, including highly nonlinear interactions in ar...

Fundamental limitations for quantum and nano thermodynamics
Abstract: The relationship between thermodynamics and statistical physics is valid in the thermodynamic limit when the number of particles becomes very large. Here we study thermodynamics in the oppo...

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...
