Superconducting Circuits and Quantum Computation
... Here we use superconducting circuits as components for quantum computing and as model systems for non-linear dynamics. Quantum computation holds the potential to solve problems currently intractable with today’s computers. Information in a quantum computer is stored on quantum variables, and that in ...

... Quantum channels and active error correction Consider an open quantum system S represented on a Hilbert space H, and write B (H) for the set of operators that act on H. A “snapshot” of a Hamiltonian-induced evolution of S is called a quantum channel. Mathematically, channels are represented by compl ...

The strange (hi)story of particles and waves
... Although this equation can be derived from the general one under the assumption of a special time dependence of the form y µ eiEt/h, there is no obvious reason for this special form. Instead of obeying the time-dependent equations, these bound states seemed to be dynamically related by Bohr’s stocha ...

... energy of particles in CSL increases with time. This growth of energy of particles provides for experimental tests of the model[18] but, from a theoretical point of view, it is desirable to have a conserved energy. Recently, I showed how to define energy associated with the w-field in CSL so that th ...
