Abstract
A quantum write controller includes an in-phase path that includes a first digital to analog converter (DAC) configured to receive an in-phase signal at a first frequency, a first mixer configured to create a third in phase frequency, a first combiner configured to combine an output of the first mixer with an output of a third mixer, and a second mixer configured to mix an output of the first combiner with a fourth in phase frequency. There is a quadrature path that includes a second DAC configured to receive a quadrature phase signal at the first frequency, a third mixer configured to create a third quadrature frequency, a second combiner configured to combine the output of the third mixer with the output of the first mixer, and a fourth mixer configured to mix an output of the second combiner with a fourth quadrature frequency.
