1. An electronic combiner circuit comprising:
a Direct Current (DC) bias input, an Alternating Current (AC) control input and a signal output, the DC bias input being arranged to receive a DC signal and couple the DC signal to the signal output in DC, the AC control input being arranged to receive an AC signal and couple the AC signal to the signal output at any frequency, the signal output being arranged to provide a combined signal for operating a quantum device;
a first conductive path arranged between the AC control input and the signal output, the first conductive path being such that a DC component of a signal provided at the AC control input is prevented from being transmitted from the AC control input to the signal output along the first conductive path; and
a second conductive path arranged between the AC control input and the signal outputs the second conductive path being such that the DC component of the signal provided at the AC control input transmits from the AC control input to the signal output along the second conductive path.
