ELECTRONIC CIRCUIT FOR DRIVING A QUANTUM CIRCUIT AND ASSOCIATED QUANTUM COMPUTER

The circuit is connected to the quantum circuit by bias lines and includes a digital-to-analog converter-DAC delivering an analog voltage (Ve); memory cells, connected in parallel at the output of the DAC, each memory cell including a switch (I1, I2, I3, I4) and a capacitor (C1, C2, C3, C4), 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 said memory cell and which runs parallel to a neighboring bias line.
