A quantum computer is a device that can arbitrarily manipulate the quantum state of a part of
itself. The field of quantum computation is largely a body of theoretical promises for some …

This tutorial is the first part of a series of two articles on quantum computation. In this first
paper, we present the field of quantum computation from a broad perspective. We review the …

Quantum computation is a rapidly progressing field today. What are its principles? In what
sense is it distinct from conventional computation? What are its advantages and …

These notes discuss the quantum algorithms we know of that can solve problems
significantly faster than the corresponding classical algorithms. So far, we have only …

1.1 Background The idea of a quantum computer was first proposed in 1981 by Nobel
laureate Richard Feynman, who pointed out that accurately and efficiently simulating …

We discuss the progress (or lack of it) that has been made in discovering algorithms for
computation on a quantum computer. Some possible reasons are given for the paucity of …

In this text we present a technical overview of the emerging field of quantum computation
along with new research results by the authors. What distinguishes our presentation from …

As the prospect of commercial quantum computers turns ever more real in recent times,
research in quantum algorithms becomes the center of attention. Due to the strong …
