Superconducting Technology

Identify key areas of research in JJ device technology for which a small amount of funding in the near term will significantly reduce uncertainty about the potential of this technology to contribute to petacomputer implementation. Specific topics include:

1. Superconducting memory for buffers, registers, and cache
2. Clock speeds of devices likely to be achieved
3. Optical connect to external world
4. Densities likely to be achieved
5. Ways of lowering cooling overhead.
