OVERVIEW

Quantum computation, the use of quantum physics to perform operations today's average computers cannot do, is a hot up-and-coming area of interest for both practical and theoretical research. This month, Special Topics examines the literature on quantum computers over the past decade and over the past two years.

The Bloch sphere is a representation of a qubit, the fundamental building block of quantum computers.

The initial data pool was constructed using the keywords "quantum comput*" OR "quantum information*" OR "quantum logic gate*" OR "quantum algorithm*" OR "qubit*" to search titles, abstracts, and keywords of original articles, reviews, and proceedings papers published between January 1, 1999 and December 31, 2009. To make the paper lists more on-target to the topic, the search term "quantum comput*" was restricted to the title only.

The highly cited papers over the past decade cover such areas as one-way quantum computing, universal quantum computing, geometric quantum computing using NMR, holonomic quantum computing, measurement-based quantum computing, quantum computing with trapped polar molecules, fault-tolerant quantum computing by anyons, physical implementation of quantum computing, and architecture for quantum computers.

The list of top papers over the past two years contains many of the topics covered on the 10-year list, but also includes cavity grids for scalable quantum computation, accuracy threshold for postselected quantum computation, light-matter qubits for a one-way quantum computer, quantum computing with alkaline earth metal atoms, and holographic quantum computers. Non-Abelian anyons and topological quantum computation and quantum computing with trapped ions are reviewed.

Methodology: The baseline time span for this database is (publication years) 1999-December 31, 2009 from the sixth bimonthly update (an 11-year period). The resulting database contained 12,386 (10 years) and 3,541 (2 years) papers; 12,269 authors; 81 nations; 634 journals; and 2,661 institutions.

Rankings: Once the database was in place, it was used to generate list of authors, journals, institutions, and nations. Rankings for author, journal, institution, and country are listed in three ways: according to total cites, total papers, and total cites/paper*. The paper thresholds and corresponding percentages used to determine scientist, institution, country, and journal rankings according to total cites/paper, and total papers respectively are as follows:

Entity Authors Institutions Nations Journals
Thresholds 12,269 2,661 81 634
Percentage: %28 %135 %33 %5*
*Unless otherwise specified, all rankings have a 5 paper threshold for all measures.
