Quantum Walk

Quantum Walk

In quantum computing, quantum walks are the quantum analogue of classical random walks. Like the classical random walk, where the walker's current state is described by a probability distribution over positions, the walker in a quantum walk is in a superposition of positions. Like classical random walks, there are two types of quantum walks, discrete-time quantum walks and continuous-time quantum walks.

Famous quotes containing the words quantum and/or walk:

    The receipt to make a speaker, and an applauded one too, is short and easy.—Take of common sense quantum sufficit, add a little application to the rules and orders of the House, throw obvious thoughts in a new light, and make up the whole with a large quantity of purity, correctness, and elegancy of style.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    You can make lots of mistakes, but if you give children avenues for creativity and joy, they will have resources to carry them through. For example, if cooking together, reading, listening to music, coloring, participating in sports, or taking a walk in the woods are paired with pleasure and closeness, throughout life doing these things will kindle old feelings of happiness an/or comfort.
    Charlotte Davis Kasl (20th century)
