Oxide-nitride heteroepitaxy for low-loss dielectrics in superconducting quantum circuits
David A. Garcia-Wetten, Mitchell J. Walker, Peter G. Lim +9
Superconducting qubits show great promise for the realization of fault-tolerant quantum computing, but lossy, amorphous dielectrics limit current technology. Identifying highly cry…
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…
Revealing inter-band electron pairing in a superconductor with spin-orbit coupling
Javier ZaldÃvar, Jon Ortuzar, Miguel Alvarado +8
Most superconducting mechanisms pair electrons within the same band, forming spin singlets. However, the discovery of multi-band superconductivity has opened new scenarios for pair…
Interplay between Majorana and Shiba states in a minimal Kitaev chain coupled to a superconductor
Miguel Alvarado, Alfredo Levy Yeyati, Ramón Aguado +1
Two semiconducting quantum dots (QDs) coupled through a superconductor constitute a minimal realisation of a Kitaev chain with Majorana zero modes (MZMs). Such MZMs can be detected…
