... In this talk, the basic toolbox of the Innsbruck quantum information processor based on a string of trapped Ca+ ions will be reviewed. For quantum information science, the toolbox operations are used to encode one logical qubit in entangled states distributed over seven trapped-ion qubits. We demons ...

COMPUTING QUANTUM PHASE TRANSITIONS PREAMBLE
... A phase transition occurs when the thermodynamic properties of a material display a singularity as a function of the external parameters. Imagine, for instance, taking a piece of ice out of the freezer. Initially, its properties change only slowly with increasing temperature. However, at 0°C, a sudd ...

Quantum Knots and Lattices, or a Blueprint for Quantum Systems
... Theorem 5.5. Two PL knots K1 and K2 are of the same knot type if and only if they have 1) The same inextensible knot type, i.e. K1 ≈ K2 , and 2) The same length, i.e., |K1 | = |K2 | . Thus, nothing from classical knot theory is lost with the above modified definition of knot type. But on the other h ...

These separations are based on concatenating small separations found for functions on small numbers of bits. For example, we have ...
