Please excuse my ignorance but I'm not sure I understand why supercondu-
ctor interconnects are such an advantage that they justify the costs.
A couple of possibilities occur to me:
1. Reduced interconnect resistivity reduces IR drops on supply
busses and so reduces chip area devoted to Busses.
2. Reduced interconnect resistivity decreases ground noise.
3. Reduced interconnect resistivity increases signal propagation
speed considering the interconnect as a stripline transmission
line.
Could somebody please educate me on which of these is most important or
add the proper considerations to this list? Thanks.
