[time-nuts] quartz / liquid nitrogen

[Mark Sims]

And you want your semiconductors to be in ceramic/lided packages with the bond 
wires flapping in free air.   Bond wires embedded in epoxy like to break...  
don't ask how I found this out  ;-)   ... it brings back bad memories... and 
makes bad memories...  Quantum chips have very elaborate/specialized bonding to 
survive liquid helium... even with that, thermal cycling still breaks them.
