Kavli Affiliate: Giordano Scappucci | First 5 Authors: Yi-Hsien Wu, Yi-Hsien Wu, , , | Summary: Silicon spin qubits are a promising platform for scalable quantum computing due to their compatibility with industrial semiconductor fabrication and the recent scaling to multi-qubit devices. Control fidelities above the 99% fault-tolerant threshold are routinely achieved, but extending high-fidelity […]
Kavli Affiliate: Simon Groblacher | First 5 Authors: Zizheng Li, Zizheng Li, , , | Summary: Amorphous silicon carbide (a-SiC) has emerged as a compelling candidate for applications in integrated photonics, known for its high refractive index, high optical quality, high thermo-optic coefficient, and strong third-order nonlinearities. 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 […]

Dobrovitski | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Shuttling of spin qubits between different locations is a key element in many prospective semiconductor systems for quantum information processing, but the shuttled qubits should be protected from decoherence created by time- and space-dependent noises. Since the paths of […]
Kavli Affiliate: Tim H. Taminiau | First 5 Authors: Abigail N. Poteshman, Abigail N. Poteshman, , , | Summary: High-throughput characterization often requires estimating parameters and model dimension from experimental data of limited quantity and quality. Such data may result in an ill-posed inverse problem, where multiple sets of parameters and model dimensions are consistent […]

Using a valence bond solid ansatz corroborated by density matrix […]
Kavli Affiliate: Natalia Chepiga | First 5 Authors: Jose Soto-Garcia, Natalia Chepiga, , , | Summary: Chains of Rydberg atoms have emerged as an amazing platform for simulating quantum physics in low dimensions. This remarkable success is due to the versatility of lattice geometries achieved by trapping neutral atoms with optical tweezers. On a given […]
