DeviceThe device is based on a stack of two-dimensional materials as illustrated on Fig. 1a, which was assembled using the standard dry transfer technique28,29,30. It consists of a 35 nm thick top hBN layer, the Bernal BLG sheet, a 28 nm thick bottom hBN, and a graphite backgate layer. The BLG was subsequently contacted with 1D edge contacts28. Three metallic top gates (3 nm Cr, 20 nm Au) were evaporated on top of the stack to define two conducting channels.

Abstract One of the key pathways toward scalability of spin-based quantum computing systems lies in achieving long-range interactions between electrons and increasing their interconnectivity. Coherent spin transport is one of the most promising strategies to achieve this architectural advantage. Experimental results have previously demonstrated high-fidelity transportation of spin qubits between two quantum dots in silicon and identified possible sources of error.
