Abstract
A quantum device comprising a plurality of qubits, a demultiplexing circuit, a common transmission line for transmitting qubit read signals to the demultiplexing circuit, and, for each qubit of the plurality, one quantum electrometer coupled to the qubit with a view to transmitting, over the common transmission line, a signal depending on a current state of the qubit and on a periodic excitation applied to the quantum electrometer. The quantum device is noteworthy in that, the periodic excitations transmitted to a group of qubits of the device being transmitted with an identical frequency, the device comprises phase-shifting means that introduce distinct phase shifts and optionally amplitude-attenuating means that introduce amplitude differences into the excitations respectively applied to the various quantum electrometers.
