The U.
S.
Army Research Office (ARO) in partnership with the Intelligence Advanced Research Projects Activity (IARPA) seeks research and development of technology and techniques for energy-efficient, high data rate transmission of digital signals between computing systems operating at room
and cryogenic temperatures.
The focus in the SuperCables program is research and demonstration of components to convert from low level electrical signals in circuits operating at a temperature of approximately 4 kelvins to conventional optical signals at room temperature and to move the information therein from one environment to the other.
Pending results of this program, IARPA may support a follow-on program to develop the complete system for bidirectional data transmission between room temperature and 4 kelvins.
