Equivalence of Topological Codes and Fast Decoding
... Theorem 1 Every 2D TSC is locally equivalent to a finite number of copies of KTC. To define precisely what we mean by local, consider an operator P acting on some qubits contained within a region of finite radius r. Then, a unitary transformation U is a local mapping if U P U † is contained within a ...

Quantum Energy Teleportation - UWSpace
... In some sense the entropy is a measure of uncertainty in a random variable. Here is a rough sketch of how this concept applies to certain situations: say we have an alphabet X and for any given message there is a probability p(x) that a given letter X is x. Then, if we consider how one could optimal ...

Quantum algorithms for shortest paths problems in structured instances
... We go one step further to improve the obtained runtimes by noticing that one does not need to do an extra Grover search to compute mins∈S d(u, s) + d(s, v). One can instead modify the way ingredient (1) is implemented and reduce the final runtime to roughly n2.5 /ℓ + ℓn2.5−ε . In the body of the pap ...

Computational power of quantum many
... In the standard model of quantum computation, a set of two-level systems initially in a product state is subjected to a unitary time-evolution in the form of sequential bipartite quantum gates [82]. At the end of the evolution, the systems are measured in some local basis, in order to read out the ...
