Quantum Criticality: competing ground states in low

Although it is certainly not appropriate to take HL as a literal model for the high temperature superconductors, it is notable [17] that many measurements of spin fluctuations in the last decade display crossovers which are very similar to those found in the vicinity of the quantum critical point in ...

Quantum Algorithms for Evaluating MIN
... We now consider the fact that the subroutines for And-Or and searching can fail. First, note that, by incurring a multiplicative factor of only O(log log(N)), each call to the And-Or and search algorithm can be amplified so that its error probability is O(1/ log(N)). This results in an O(W (N) log(N ...
