Erasure conversion for singlet-triplet spin qubits enables high-performance shuttling-based quantum error correction
Adam Siegel, Simon Benjamin
Fast and high fidelity shuttling of spin qubits has been demonstrated in semiconductor quantum dot devices. Several architectures based on shuttling have been proposed; it has been…
Harnessing electron motion for global spin qubit control
Hamza Jnane, Adam Siegel, M. Fernando Gonzalez-Zalba
Silicon spin qubits are promising candidates for building scalable quantum computers due to their nanometre scale features. However, delivering microwave control signals locally to…
Looped Pipelines Enabling Effective 3D Qubit Lattices in a Strictly 2D Device
Zhenyu Cai, Adam Siegel, Simon Benjamin
Many quantum computing platforms are based on a two-dimensional physical layout. Here we explore a concept called looped pipelines which permits one to obtain many of the advantage…
Snakes on a Plane: mobile, low dimensional logical qubits on a 2D surface
Adam Siegel, Zhenyu Cai, Hamza Jnane +4
Recent demonstrations indicate that silicon-spin QPUs will be able to shuttle physical qubits rapidly and with high fidelity - a desirable feature for maximising logical connectivi…
Towards early fault tolerance on a 2N array of qubits equipped with shuttling
Adam Siegel, Armands Strikis, Michael Fogarty
It is well understood that a two-dimensional grid of locally-interacting qubits is a promising platform for achieving fault tolerant quantum computing. However in the near-future,…
