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…
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…
Signatures of Majorana protection in a three-site Kitaev chain
Alberto Bordin, Chun-Xiao Liu, Tom Dvir +14
Majorana zero modes (MZMs) are non-Abelian excitations predicted to emerge at the edges of topological superconductors. One proposal for realizing a topological superconductor in o…
A two-site Kitaev chain in a two-dimensional electron gas
Sebastiaan L. D. ten Haaf, Qingzhen Wang, A. Mert Bozkurt +9
Artificial Kitaev chains can be used to engineer Majorana bound states (MBSs) in superconductor-semiconductor hybrids. In this work, we realize a two-site Kitaev chain in a two-dim…
Enhancing the excitation gap of a quantum-dot-based Kitaev chain
Chun-Xiao Liu, A. Mert Bozkurt, Francesco Zatelli +3
Connecting double quantum dots via a semiconductor-superconductor hybrid segment offers a platform for creating a two-site Kitaev chain that hosts a pair of "poor man's Majoranas"…
Controlled crossed Andreev reflection and elastic co-tunneling mediated by Andreev bound states
Alberto Bordin, Guanzhong Wang, Chun-Xiao Liu +12
A short superconducting segment can couple attached quantum dots via elastic co-tunneling (ECT) and crossed Andreev reflection (CAR). Such coupled quantum dots can host Majorana bo…
Triplet correlations in Cooper pair splitters realized in a two-dimensional electron gas
Qingzhen Wang, Sebastiaan L. D. ten Haaf, Ivan Kulesh +4
Cooper pairs occupy the ground state of superconductors and are typically composed of maximally entangled electrons with opposite spin. In order to study the spin and entanglement…
Realization of a minimal Kitaev chain in coupled quantum dots
Tom Dvir, Guanzhong Wang, Nick van Loo +14
Majorana bound states constitute one of the simplest examples of emergent non-Abelian excitations in condensed matter physics. A toy model proposed by Kitaev shows that such states…
Singlet and triplet Cooper pair splitting in hybrid superconducting nanowires
Guanzhong Wang, Tom Dvir, Grzegorz P. Mazur +9
In most naturally occurring superconductors, electrons with opposite spins are paired up to form Cooper pairs. This includes both conventional -wave superconductors such as alum…
