A detailed experimental analysis of a free-propagating light pulse prepared in a “Schrödinger kitten” state, which is defined as a quantum superposition of “classical” coherent states with small amplitudes, providing an essential tool for quantum information processing.Expand

Quantum tomography is the process of reconstructing the ensemble average of an arbitrary operator (observable or not, including the density matrix), which may not be directly accessible by feasible… Expand

The state of a physical system is the mathematical object that provides a complete information on the system. The knowledge of the state is equivalent to know the result of any possible measurement… Expand

Coherently Controlling Large Cats The control and manipulation of quantum information based on superconducting circuits is an attractive route because of the possibility of scale-up. Vlastakis et al.… Expand

The possibility of “measuring” quantum states has been already considered by W. Pauli [1], who wrote in a footnote: “The mathematical problem, as to whether for given functions W (x) and W (p), the… Expand
