Comments on quant-ph/0506137: Fast quantum search algorithms by qubit comparisons exploiting global phase interference
L. A. B. Kowada, C. M. H. de Figueiredo, R. Portugal +1
Recently, Andreas de Vries proposed a quantum algorithm that would find an element in an unsorted database exponentially faster than Grover's algorithm. We show that de Vries' algo…
Information Processing in Brain Microtubules
Jean Faber, Renato Portugal, Luiz Pinguelli Rosa
Models of the mind are based on the possibility of computing in brain microtubules. From this point of view, information processing is the fundamental issue for understanding the b…
Genetic Algorithms and Quantum Computation
Gilson A. Giraldi, Renato Portugal, Ricardo N. Thess
Recently, researchers have applied genetic algorithms (GAs) to address some problems in quantum computation. Also, there has been some works in the designing of genetic algorithms…
Grover's Algorithm: Quantum Database Search
C. Lavor, L. R. U. Manssur, R. Portugal
We review Grover's algorithm by means of a detailed geometrical interpretation and a worked out example. Some basic concepts of Quantum Mechanics and quantum circuits are also revi…
Group-theoretic Approach for Symbolic Tensor Manipulation: I. Free Indices
R. Portugal, B. F. Svaiter
We describe how Computational Group Theory provides tools for manipulating tensors in explicit index notation. In special, we present an algorithm that puts tensors with free indic…
