The article discusses advancements in the control of silicon spin qubits using a heterogeneously integrated cryo-CMOS chip. This chip operates at milli-kelvin temperatures, allowing for improved integration of control systems while managing thermal and electrical noise challenges. The chiplet-style approach separates the noisy control circuitry from the qubits, simplifying the wiring complexity. As control systems generate trillions of signals per second, this innovation represents a crucial step towards scalable, utility-scale quantum computing where millions of qubits are required, capitalizing on silicon's advantages in size and coherence time.
"Heterogeneous, 'chiplet-style' integration, as opposed to monolithic circuits, decouples the hot and noisy control system from sensitive qubits."
"The control of MOS-style silicon spin qubits using a heterogeneously integrated cryo-CMOS chip operating at milli-kelvin temperatures represents a significant advancement in qubit control."
