Field-free dual superconducting diode via photon-assisted interference
Laura Borgongino, Rubén Seoane Souto, José Luis del Olmo +4
Non-reciprocal transport underpins key functionalities in signal processing and logic; however, conventional semiconductor diodes exhibit reduced performance at sub-Kelvin temperat…
All-electrical dephasing-protected spin qubits in altermagnets
José Carlos Abadillo-Uriel, Andrea Maiani, Alberto Cortijo +2
We propose altermagnetic semiconductors as a platform for field-free, all-electrically controlled spin qubits in gate-defined quantum dots. The momentum-dependent spin splitting of…
Lindblad theory of linear response susceptibility and dispersive readout in minimal Kitaev junctions
Tobias Kuhn, Raffael L. Klees, Ramón Aguado +1
The field of hybrid superconductor-semiconductor quantum dots is advancing toward the development of functional devices that leverage the advantages of both types of materials. How…
Assessing Majorana states and qubits through quantum capacitance
Rodrigo A. Dourado, Ramón Aguado, Jeroen Danon +2
Quantum capacitance (QC) has recently emerged as a promising tool for parity readout in topological qubits based on Majorana bound states (MBSs). Here, we show that this capability…
Optimal Majoranas in Mesoscopic Kitaev Chains
M. Alvarado, R. Seoane Souto, María José Calderón +1
Kitaev chains realized in quantum dots coupled via superconducting segments provide a controllable platform for engineering Majorana zero modes (MZMs). In these systems, subgap sta…
Granular aluminum induced superconductivity in germanium for hole spin-based hybrid devices
Giorgio Fabris, Paul Falthansl-Scheinecker, Devashish Shah +19
In superconductor-semiconductor hybrid structures, superconductivity and spin polarization are competing effects as magnetic fields break Cooper pairs. They can be combined using t…
