A fault-tolerant quantum processor may be configured using stationary qubits interacting
only with their nearest neighbours, but at the cost of significant overheads in physical qubits …

We detect correlations in qubit-energy fluctuations of non-neighboring qubits defined in
isotopically purified Si/Si-Ge quantum dots. At low frequencies (where the noise is …

The strong spin-orbit coupling in hole spin qubits enables fast and electrically tunable gates,
but at the same time enhances the susceptibility of the qubit to charge noise. Suppressing …

We identify the dominant source for low-frequency spin qubit splitting noise in a highly
isotopically-purified silicon device with an embedded nanomagnet and a spin echo decay …

The encoding of qubits in semiconductor spin carriers has been recognized as a promising
approach to a commercial quantum computer that can be lithographically produced and …
