Progress in superconductor-semiconductor topological Josephson junctions

WF Schiela, P Yu, J Shabani - PRX Quantum, 2024 - APS
Majorana bound states (MBSs) are quasiparticles that are their own antiparticles. They are
predicted to emerge as zero-energy modes localized at the boundary of a topological …

Andreev (or superconducting) spin qubits (ASQs) have recently emerged as a promising
qubit platform that combines superconducting circuits with semiconductor spin degrees of …

Many-body quantum dynamics of spin-orbit coupled Andreev states in a Zeeman field

K Zatsarynna, A Nava, A Zazunov, R Egger - Physical Review B, 2024 - APS
We provide a theoretical framework to describe the quantum many-body dynamics of
Andreev states in Josephson junctions with spin-orbit coupling and a magnetic Zeeman …

Generalized transmon Hamiltonian for Andreev spin qubits

L Pavešić, R Žitko - Physical Review B, 2024 - APS
We solve the problem of an interacting quantum dot embedded in a Josephson junction
between two superconductors with finite charging energy described by the transmon …
