Quantum state tomography through multi-frequency Josephson effect
Xian-Peng Zhang, Ting-Rui Hu, Zhen-Biao Yang +2
Macroscopic quantum effects emerge when the coherent behavior of countless microscopic quantum states manifests collectively at a visible scale, as exemplified by the supercurrent…
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…
Microwave Response of the Superconducting Diode Effect in Proximitized Bilayer Graphene Interferometers
Shili Yan, Rubén Seoane Souto, Yi Luo +7
Microwave irradiation has emerged as a promising means to tune the superconducting diode effect (SDE) in Josephson junction devices. Previous experimental studies have mainly focus…
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…
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…
