Article Synopsis
- Quantum processor designs need to scale up qubit numbers while ensuring strong connectivity and high accuracy in operations.
- Current semiconductor spin qubit arrays face limitations due to wiring and interference, but the new SpinBus architecture addresses these by connecting qubits through electron shuttling and using lower frequencies for better performance.
- Simulations show that the SpinBus approach can support at least 144 qubits with high fidelity, potentially enabling future quantum processors to meet the demands of scalable quantum computing.
The connectivity within single carrier information-processing devices requires transport and storage of single charge quanta. Single electrons have been adiabatically transported while confined to a moving quantum dot in short, all-electrical Si/SiGe shuttle device, called quantum bus (QuBus). Here we show a QuBus spanning a length of 10 μm and operated by only six simply-tunable voltage pulses.
