Single qubit measurements with an asymmetric single-electron transistor
Single qubit measurements with an asymmetric single-electron transistor
We investigate qubit measurements using a single-electron transistor (SET). Applying the Schr\"odinger equation to the entire system we find that an asymmetric SET is considerably more efficient than a symmetric SET. Yet, its efficiency does not reach that of an ideal detector even in the large asymmetry limit. We also …
