Operating semiconductor qubits without individual barrier gates
A. S. Ivlev, D. R. Crielaard, M. Meyer +8
Semiconductor spin qubits have emerged as a promising platform for quantum computing, following a significant improvement in their control fidelities over recent years. Increasing…
Baseband control of single-electron silicon spin qubits in two dimensions
Florian K. Unseld, Brennan Undseth, Eline Raymenants +9
Micromagnet-enabled electric-dipole spin resonance (EDSR) is an established method of high-fidelity single-spin control in silicon. However, the resulting architectural limitations…
Operating semiconductor quantum processors with hopping spins
Chien-An Wang, Valentin John, Hanifa Tidjani +16
Qubits that can be efficiently controlled are essential for the development of scalable quantum hardware. While resonant control is used to execute high-fidelity quantum gates, the…
Coupled vertical double quantum dots at single-hole occupancy
Alexander Ivlev, Hanifa Tidjani, Stefan Oosterhout +3
Gate-defined quantum dots define an attractive platform for quantum computation and have been used to confine individual charges in a planar array. Here, we demonstrate control ove…
