The design and benchmarking of quantum computer architectures traditionally rely on
practical hardware restrictions, such as gate fidelities, control, and cooling. At the theoretical …

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 connectivity …

Semiconductor quantum dot spin qubits hold significant potential for scaling to millions of
qubits for practical quantum computing applications, as their structure highly resembles the …

We propose a singlet-only always-on gapless exchange (SAGE) spin qubit that encodes a
single qubit in the spins of four electrons while allowing universal baseband control. While …
