Summary
Scientists have identified the origin of noise in spin qubit quantum processors, which are a promising platform for quantum computing. Spin qubits encode quantum information in the spin state of an electron, offering long coherence times and compatibility with semiconductor manufacturing. The research focuses on quantum dots—nanoscale semiconductor structures that act as controllable artificial atoms—and recent advances have enabled high-fidelity single- and two-qubit gate operations exceeding key thresholds.
