Abstract This Technical Review collects values of selected performance characteristics of
semiconductor spin qubits defined in electrically controlled nanostructures. The …

Quantum computation features known examples of hardware acceleration for certain
problems, but is challenging to realize because of its susceptibility to small errors from noise …

Charge noise in the host semiconductor degrades the performance of spin-qubits and poses
an obstacle to control large quantum processors. However, it is challenging to engineer the …

Building a fault-tolerant quantum computer will require vast numbers of physical qubits. For
qubit technologies based on solid-state electronic devices,–, integrating millions of qubits in …

Electron spins in silicon quantum dots are promising qubits due to their long coherence

Small spin-qubit registers defined by single electrons confined in Si/SiGe quantum dots
operate successfully and connecting these would permit scalable quantum computation …

Visual attention can be voluntarily directed toward stimuli and is attracted by stimuli that are
emotionally significant. The present study explored the case when both processes coincide …

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 …
