Quantum capacitance with an auxiliary quantum dot measures ground-state energy splitting and Majorana overlap in topological qubits via peak positions and magnitudes in even and odd parity sectors.
A Fourier-engineered cos(2φ) qubit achieves spectral agreement with theory but its energy relaxation is limited by 1/f flux noise from residual first-harmonic fluctuations, unlike similar fluxonium qubits.
Multi-objective Bayesian optimization of Si-spike-enriched Ge heterostructures predicts up to 1000x stronger spin-orbit interaction and 100x better spin-qubit quality factors than state-of-the-art Ge/SiGe wells.
For quantum-dot Kitaev chains, the optimal Majorana sweet-spot—well-localized Majoranas together with a large excitation gap—occurs at the parity-crossing of the spin-split Andreev bound state in the mesoscopic superconducting segment.
Granular aluminum induces a hard, magnetically resilient superconducting gap of 305 μeV in germanium, allowing Zeeman splitting of YSR states beyond 50 μeV and g-tensor tunability for hole-based hybrid quantum devices.
