Gate reflectometry in a minimal Kitaev chain device
Yining Zhang, Ivan Kulesh, Sebastiaan L. D. ten Haaf +5
Hybrid quantum dot (QD)-superconductor system can be used to realize Majorana zero modes in artificial Kitaev chains. These chains provide a promising platform for the realization…
Single-shot parity readout of a minimal Kitaev chain
Nick van Loo, Francesco Zatelli, Gorm O. Steffensen +12
Protecting qubits from noise is essential for building reliable quantum computers. Topological qubits offer a route to this goal by encoding quantum information non-locally, using…
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…
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…
Scattering as a quantum metrology problem: a quantum walk approach
Francesco Zatelli, Claudia Benedetti, Matteo G. A. Paris
We address the scattering of a quantum particle by a one-dimensional barrier potential over a set of discrete positions. We formalize the problem as a continuous-time quantum walk…
