Revealing topological protection through unprotected operations in a Majorana parity qubit
Sebastian Miles, Juan Daniel Torres Luna, Francesco Zatelli +7
A recent experiment reported coherent parity oscillations between minimal Kitaev chains, demonstrating a Majorana parity qubit (arXiv:2607.09511). Operations on this qubit are cont…
Majorana parity qubit in coupled minimal Kitaev chains
Francesco Zatelli, Bart Roovers, Nick van Loo +11
Majorana zero modes provide a route to fault-tolerant qubits by encoding information non-locally in fermion parity. Their sensitivity to noise is expected to decrease exponentially…
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…
Effective Hamiltonians for Ge/Si core/shell nanowires from higher order perturbation theory
Sebastian Miles, A. Mert Bozkurt, Dániel Varjas +1
We theoretically explore the electronic structure of holes in cylindrical Germanium/Silicon core/shell nanowires using a perturbation theory approach. The approach yields a set of…
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…
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…
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…
Scaling up a sign-ordered Kitaev chain without magnetic flux control
Chun-Xiao Liu, Sebastian Miles, Alberto Bordin +4
Quantum dot-superconductor arrays have emerged as a new and promising material platform for realizing topological Kitaev chains. So far, experiments have implemented a two-site cha…
Interaction-induced strong zero modes in short quantum dot chains with time-reversal symmetry
A. Mert Bozkurt, Sebastian Miles, Sebastiaan L. D. ten Haaf +3
We theoretically explore the emergence of strong zero modes in a two-site chain consisting of two quantum dots coupled due to a central dot that mediates electron hopping and singl…
Kitaev chain in an alternating quantum dot-Andreev bound state array
Sebastian Miles, David van Driel, Michael Wimmer +1
We propose to implement a Kitaev chain based on an array of alternating normal and superconductor hybrid quantum dots embedded in semiconductors. In particular, the orbitals in the…
Fermionic quantum computation with Cooper pair splitters
Kostas Vilkelis, Antonio Manesco, Juan Daniel Torres Luna +3
We propose a practical implementation of a universal quantum computer that uses local fermionic modes (LFM) rather than qubits. The device layout consists of quantum dots tunnel co…
