Abstract Quantum links can interconnect qubit registers and are therefore essential in networked quantum computing. Semiconductor quantum dot qubits have seen significant progress in the high-fidelity operation of small qubit registers but establishi

The difficulty in obtaining a superconducting gap free of subgap states has hindered progress with hybrid superconductor-semiconductor devices in germanium. Here, this challenge is addressed by using a germanosilicide parent superconductor to contact

Charge noise degrades the performance of spin qubits hindering scalability. Here the authors engineer the heterogeneous material stack in 28Si/SiGe gate-defined quantum dots, to improve the scattering properties and to reduce charge noise.

Spin qubits in Si/SiGe quantum dots suffer from variability in the valley splitting which will hinder device scalability. Here, by using 3D atomic characterization, the authors explain this variability by random Si and Ge atomic fluctuations and prop

A coherent quantum link between distant quantum processors is desirable for scaling up of quantum computation. Noiri et al. demonstrate a strategy to link distant quantum processors in silicon, by implementing a shuttling-based two-qubit gate between
