On-chip cryogenic multiplexing of Si/SiGe quantum devices
On-chip cryogenic multiplexing of Si/SiGe quantum devices
The challenges of operating qubits in a cryogenic environment point to a looming bottleneck for large-scale quantum processors, limited by the number of input-output connections. Classical processors solve this problem via multiplexing; however, on-chip multiplexing circuits have not been shown to have similar benefits for cryogenic quantum devices. In this …
