QUANTUM COMPUTING: SUPERCONDUCTING QUANTUM BITS (QUBITS)

SPECIAL TOPICS

High-Temperature Superconductors - February 2009

Research Front Maps

Research front maps are diagrammatic representations of the core papers comprising each front. They are selected from the current Research Front set that are relevant to the featured special topic. The title for this Research Front Map is "SUPERCONDUCTING QUBITS," containing 31 core papers. Source dates: 1998-August 31, 2008 (fifth bimonthly period 2008).

Each circle represents a highly cited paper whose bibliographic information is displayed when the user clicks on the circle. The solid lines between circles represent the strongest co-citation links for each paper (that is, indicating that the papers are frequently cited together); weaker links are indicated by dashed lines. Papers close to each other on the map are generally more highly co-cited. The most recent paper(s) are indicated in pink. Annotations may have been added to this map which represent the main research themes. These appear as labels attached to specific regions on the maps.

Note: For best results use the "landscape orientation" option when printing this page.
