| contents | To build a large scale quantum circuit comprising millions of cryogenic qubits will require an efficient way to supply large numbers of classic control signals. Given the limited number of direct connections allowed from room temperature, multiple level of signal multiplexing becomes essential. The stacking of hardware to accomplish this task is highly dependent on the lowest level implementation of control electronics, of which an open question is the feasibility of mK integration. Such integration is preferred for signal transmission and wire interconnection, provided it is not limited by the large power dissipation involved. Novel cryogenic electronics that prioritises power efficiency has to be developed to meet the tight thermal budget. In this paper, we present a power efficient approach to implement charge-locking array. |
