The curse of measurement

Back-action effects influence transistors

 

Cutting-edge computer processors consist of 1.4 billion transistors. Such tiny structures, however, have a major drawback: The read-out process can influence their states in an uncontrolled way. A new model is able to detect and to avoid these “back-action effects” particularly at the quantum level.
