Subject: Moore's Law will hit an insurmountable speed limit - in  
eighty years, max

09. Quantum speed limit , Nature

Excerpts: The processing speed of computer chips has doubled almost
every two
years for the past 40, as engineers have crammed ever more transistors
into
smaller circuits. But according to Lev Levitin and Tommaso Toffoli of
Boston
University in Massachusetts, chips will ultimately hit a roadblock,
limited by
the minimum time it takes for a particle to flip from one quantum
state to
another — a fundamental step in any information system. (...) Levitin
says
that, at the current doubling pace, computing speed will reach this
limit in
about 80 years.
