New era for quantum electronics
Michel Devoret · Physics World · 2001
The miniaturization and increase in speed of electronic devices was one of the most spectacular achievements of 20th-century technology. We now have computer chips that contain billions of transistors and can perform operations in a billionth of a second. Will the constant improvement in performance that we have witnessed in the last few decades continue? There is no clear answer to this question yet, but chip developers are beginning to feel pressure from various fundamental limits. One important limitation is the amount of power that is dissipated per unit area of the chip.
