Abstract

A quantum device includes multiple spin qubits, multiple electrometers, each being capacitively coupled to one of the spin qubits, multiple injection-locked oscillators, each being coupled to one of the electrometers and designed to transmit an excitation signal to the electrometer to which it is coupled, each excitation signal having a different frequency, an amplification circuit comprising at least one amplifier, wherein the device comprises a feedback loop coupling the output of the amplification circuit to an input of each injection-locked oscillator and through which an injection signal flows, each injection-locked oscillator being designed to receive the injection signal and, as a function of the injection signal, maintain or decrease its excitation signal.
