Furthermore, a-SiC can be easily deposited via CMOS-compatible […]
Kavli Affiliate: Eliska Greplova | First 5 Authors: Christian Kraglund Andersen, Christian Kraglund Andersen, , , | Summary: It is widely accepted that quantum error correction is essential for realizing large-scale fault-tolerant quantum computing. Recent experiments have demonstrated error correction codes operating below threshold, primarily using local planar codes such as the surface code and […]
Kavli Affiliate: Menno Veldhorst | First 5 Authors: Cecile X. Yu, Cecile X. Yu, , , | Summary: Germanium spin qubits exhibit strong spin-orbit interaction, which allow for high-fidelity qubit control, but also provide a strong dependence on the magnetic field. Superconducting vector magnets are often used to minimize dephasing due to hyperfine interactions and […]
