SOLID STATE QUANTUM COMPUTING USING SPECTRAL HOLES
... Figure 1: Schematic Illustration of coupling inhomogeneously broadened atoms using spectral selectivity. The top figure shows a small volume of a crystal, selected by the intersection of the cavity mode and the control laser beams. The bottom figure shows how the atoms can be indexed in terms of the ...

Some Basic Aspects of Fractional Quantum Numbers
... Given this form, quantization of qbare and qbare in integers does not imply that renormalized charges are rationally related. In particular, suppose that the first charge is associated with local fields, while the second is topological. Then ratio of renormalized charges for a general state, and the ...

Lecture 8: Period Finding: Simon`s Problem over ZN 1 Problem
... As usual, we have oracle access to f , and we denote the oracle by Of . For this problem, it is most convenient to work with the oracle which behaves as follows: Of (|xi|bi) = |xi|b ⊕ f (x)i, where b is an m-qubit string. We have the promise that f is periodic; namely for some s ∈ ZN \ {0}, f (x) = ...

We want the states which violate the most number of states to “cost” the most energy. In the USA case there should be a single diagonal element with value zero. This is the ...
