To Scale Up or To Scale Out: Evaluating Space-Time Costs of Compiled Logical Circuits on Modular Superconducting Quantum Processors
Nikiforos Paraskevopoulos, Sebastian de Bone, Mick Christophersen +4
Modular integration has emerged as the main pathway for scaling superconducting quantum processing units (QPUs) beyond the constraints of fabrication yield and physical footprint.…
Cross-Platform Autonomous Control of Minimal Kitaev Chains
David van Driel, Rouven Koch, Vincent P. M. Sietses +21
Contemporary quantum devices are reaching new limits in size and complexity, allowing for the experimental exploration of emergent quantum modes. However, this increased complexity…
Quantifying robustness and locality of Majorana bound states in interacting systems
William Samuelson, Juan Daniel Torres Luna, Sebastian Miles +4
Protecting qubits from perturbations is a central challenge in quantum computing. Topological superconductors with separated Majorana bound states (MBSs) provide a strong form of p…
Coherence limitations of a Fourier-engineered transmon qubit
Nataliia K. Zhurbina, Siddharth Singh, Lukas J. Splitthoff +4
Intrinsically protected superconducting qubits are a promising route toward enhancing coherence times and advancing hardware towards applications in quantum computing. The $\cos(2Ï…
Braiding Majoranas in a linear quantum dot-superconductor array: Mitigating the errors from Coulomb repulsion and residual tunneling
Sebastian Miles, Francesco Zatelli, A. Mert Bozkurt +2
Exchanging the positions of two non-Abelian anyons transforms between many-body wavefunctions within a degenerate ground-state manifold. This behavior is fundamentally distinct fro…
Probing ground-state degeneracies of a strongly interacting Fermi-Hubbard model with superconducting correlations
Sebastiaan L. D. ten Haaf, Sebastian Miles, Qingzhen Wang +6
The Fermi-Hubbard model and its rich phase diagram naturally emerges as a description for a wide range of electronic systems. Recent advances in semiconductor-superconductor hybrid…
