Novel qubits in hybrid semiconductor-superconductor nanostructures
Marta Pita-Vidal, Rubén Seoane Souto, Srijit Goswami +4
Hybrid semiconductor-superconductor qubits have recently emerged as a promising alternative to traditional platforms, combining material advantages with device-level tunability. A…
Fast-driving spectroscopy of current-phase relationships of individual Josephson elements
Maxim Tjøtta, Devashish Shah, Kanishk Modi +4
Extracting the current-phase relationship (CPR) of a single superconducting junction is challenging in practice and traditionally involves embedding the junction in a larger superc…
Machine-learned tuning to protected states by probing noise resilience
Rodrigo A. Dourado, Nicolás Martínez-Valero, Jacob Benestad +3
Protected states are promising for quantum technologies due to their intrinsic resilience against noise. However, such states often emerge at discrete points or small regions in pa…
Measuring coherence factors of states in superconductors through local current
Rodrigo A. Dourado, Jeroen Danon, Martin Leijnse +1
The coherence factors of quasiparticles in a superconductor determine their properties, including transport and susceptibility to electric fields. In this work, we propose a way to…
Adiabatic nonabelian braiding of imperfect Majoranas
Maximilian Nitsch, Viktor Svensson, William Samuelson +5
Demonstration of a nontrivial result of quasiparticle exchange (or braiding) is usually considered the definitive proof of a topological phase with nonabelian excitations, such as…
Characterizing local Majorana properties using Andreev states
Miguel Alvarado, Alfredo Levy Yetati, Ramón Aguado +1
We propose using Andreev bound states (ABS) as spectroscopic probes to characterize Majorana zero modes (MZMs) in quantum-dot based minimal Kitaev chains. Specifically, we show tha…
Quantum state transfer and maximal entanglement between distant qubits using a minimal quasicrystal pump
Arnob Kumar Ghosh, Rubén Seoane Souto, Vahid Azimi-Mousolou +2
Coherent quantum state transfer over macroscopic distances between non-neighboring elements in quantum circuits is a crucial component to increase connectivity and simplify quantum…
Flux-tunable parity-protected qubit based on a single full-shell nanowire Josephson junction
G. Giavaras, Ruben Seoane Souto, Maria Jose Calderon +1
Leveraging the higher harmonics content of the Josephson potential in a superconducting circuit offers a promising route in the search for new qubits with increased protection agai…
Majorana sweet spots in 3-site Kitaev chains
Rodrigo A. Dourado, Martin Leijnse, Rubén Seoane Souto
Minimal Kitaev chains, composed of two quantum dots (QDs) connected via a superconductor, have emerged as an attractive platform to realize Majorana bound states (MBSs). These exci…
