- Fast sensing of double-dot charge arrangement and spin state with a . . .
Single-shot measurement of the charge arrangement and spin state of a double quantum dot are reported with measurement times down to 100 ns Sensing uses radio-frequency reflectometry of a proximal quantum dot in the Coulomb blockade regime
- Fast sensing of double-dot charge arrangement and spin state with a . . .
In this Rapid Communication, we demonstrate the use of a sensor quantum dot for fast charge and two-electron spin-state measurement in a GaAs double quantum dot, biased near the 1,1 - 0,2 charge transition We compare the perfor-mance of the SQD to conventional QPC sensors for dc and radio-frequency rf measurement
- [1001. 3585] Fast sensing of double-dot charge arrangement and spin . . .
Sensing uses radio-frequency reflectometry of a proximal quantum dot in the Coulomb blockade regime The sensor quantum dot is up to 30 times more sensitive than a comparable quantum point contact sensor, and yields three times greater signal to noise in rf single-shot measurements

In this Communication, we demonstrate the use of a sensor quantum dot for fast charge and two-electron spin-state measurement in a GaAs double quantum dot, biased near the (1,1)- (0,2) charge transition We compare the performance of the SQD to conventional quantum point contact (QPC) sensors for dc and radio-frequency (rf) measurement
