Flexible Logical Operations in Silicon Spin Qubit Architectures with Shuttling
Silicon spin qubits allow the implementation of multiple quantum error correcting codes, including the surface code and ultra-high-rate qLDPC codes. We describe how different logical operations can be implemented on Quantum Motion’s looped pipeline architecture enabled by qubit shuttling and the standard CMOS manufacturing process. This architecture presents unique ways to compute the number of reliable quantum operations and hence the size and cost of useful quantum applications. We also discuss the advantages of silicon spin qubits more broadly and propose key metrics to include alongside QuOps to meaningfully characterise a quantum computing system.
