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…
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…
Quantum capacitance and parity switching of a quantum-dot-based Kitaev chain
Chun-Xiao Liu
An array of quantum dots coupled via superconductivity provides a new platform for creating Kitaev chains with Majorana zero modes, offering a promising avenue toward topological q…
Using Andreev bound states and spin to remove domain walls in a Kitaev chain
Wietze D. Huisman, Sebastiaan L. D. ten Haaf, Chun-Xiao Liu +6
Quantum dot-superconductor hybrids have been established as a suitable platform for realizing Kitaev chains hosting Majorana bound states. Implementing these structures in a qubit…
Pareto-optimality of Majoranas in hybrid platforms
Juan Daniel Torres Luna, Sebastian Miles, A. Mert Bozkurt +4
To observe Majorana bound states, and especially to use them as a qubit, requires careful optimization of competing quality metrics. We systematically compare Majorana quality in p…
Probing Majorana localization of a phase-controlled three-site Kitaev chain with an additional quantum dot
Alberto Bordin, Florian J. Bennebroek Evertsz', Bart Roovers +11
Few-site implementations of the Kitaev chain offer a minimal platform to study the emergence and stability of Majorana bound states. Here, we realize two- and three-site chains in…
