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…
Machine-learned tuning to protected states by probing noise resilience
Rodrigo A. Dourado, Nicolás MartÃnez-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…
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…
Two-site Kitaev sweet spots evolving into topological islands
Rodrigo A. Dourado, J. Carlos Egues, Poliana H. Penteado
Artificial Kitaev chains based on arrays of quantum dots are promising platforms for realizing Majorana Bound States (MBSs). In a two-site Kitaev chain, it is possible to find thes…
