In quantum computing, and because all of the states of the quantum system can exist simultaneously, all of the paths of the
quantum computations tree from the root to the leaves occur in parallel and only after measurement a single path will be observed
as the whole system's composite state will collapse into that single path. From a computation perspective, each path in the
tree of quantum computing is a single processing, and thus a massive computational parallelism exists with massive number
of calculations performed simultaneously. Systolic devices provide inexpensive but massive calculation power, and are cost-effective,
high-performance, and special-purpose systems that have wide range of implementations such as in solving several regular and
compute-bound problems containing repetitive multiple operations on large arrays of data. This book presents research in the
study of parallel computing.
