CPC G06N 10/40 (2022.01) [G06N 10/20 (2022.01)] | 17 Claims |
1. A quantum device comprising:
several spin qubits each comprising at least one quantum dot, the qubits being arranged by forming a matrix of qubits;
several electrometers each electrostatically coupled to a potential well of the quantum dot of one of the spin qubits;
circuits configured to apply at least one AC excitation signal to at least one input electrode of each of the electrometers, configured such that a value of at least one parameter from a frequency, phase and maximum amplitude of each of the excitation signals is different from that of the other excitation signals; each circuit being configured to apply at least one AC excitation signal being configured to apply a same excitation signal to input electrodes of electrometers coupled to qubits arranged on a same row of the matrix of qubits;
a transimpedance amplifier comprising an input electrically coupled to output electrodes, distinct from the input electrodes, of at least two of the electrometers to which output signals are to be delivered; and
a demultiplexing circuit including an input electrically coupled to an output of the transimpedance amplifier, and configured to demultiplex the output signals to be delivered by the electrometers.
