Abstract
The circuit is connected to the quantum circuit by bias lines and includes a digital-to-analog converter—DAC delivering an analog voltage; memory cells, connected in parallel at the output of the DAC, each memory cell including a switch and a capacitor, the capacitor storing a level of potential at which to maintain a bias line connected to the output of the memory cell; and a device for generating control signals generating, in synchronization with the DAC, a control signal for each switch of each memory cell, the control signal, a value of the capacitor of a memory cell being selected so as to make negligible a parasitic capacitor affecting the bias line connected to the memory cell and which runs parallel to a neighboring bias line.
