Strong-coupling theory of quantum dot Josephson junctions: role of the residual quasiparticle
Luka Pavešič, Ramón Aguado, Rok Žitko
We consider an interacting quantum dot strongly coupled to two superconducting leads in a Josephson junction geometry. By defining symmetry-adapted superpositions of states from th…
Flux-tunable supercurrent in full-shell nanowire Josephson junctions
G. Giavaras, R. Aguado
Full-shell nanowires (a semiconducting core fully wrapped by an epitaxial superconducting shell) have recently been introduced as promising hybrid quantum devices. Despite this, ho…
Spectroscopy of spin-split Andreev levels in a quantum dot with superconducting leads
Arno Bargerbos, Marta Pita-Vidal, Rok Žitko +9
We use a hybrid superconductor-semiconductor transmon device to perform spectroscopy of a quantum dot Josephson junction tuned to be in a spin-1/2 ground state with an unpaired qua…
Direct manipulation of a superconducting spin qubit strongly coupled to a transmon qubit
Marta Pita-Vidal, Arno Bargerbos, Rok Žitko +9
Spin qubits in semiconductors are currently one of the most promising architectures for quantum computing. However, they face challenges in realizing multi-qubit interactions over…
Majorana-like Coulomb spectroscopy in the absence of zero bias peaks
Marco Valentini, Maksim Borovkov, Elsa Prada +7
Hybrid semiconductor-superconductor devices hold great promise for realizing topological quantum computing with Majorana zero modes (MZMs). However, multiple claims of Majorana det…
Singlet-doublet transitions of a quantum dot Josephson junction detected in a transmon circuit
Arno Bargerbos, Marta Pita-Vidal, Rok Žitko +10
We realize a hybrid superconductor-semiconductor transmon device in which the Josephson effect is controlled by a gate-defined quantum dot in an InAs/Al nanowire. Microwave spectro…
