Using quantum dot superconductor hybrids in nanowires we demonstrated singlet and triplet Cooper pair splitting (Nature) and achieved strong interactions between the dots to create a minimal Kitaev chain with unpaired Majorana zero modes (Nature).

We showed theoretically (Phys. Rev. Lett.) and experimentally (arXiv) how the interactions between the sites of the Kitaev chain can be controlled via Andreev bound states.

Using two-dimensional electron gases we demonstrated the feasibility of creating Kitaev chains on a scalable and flexible platform (arXiv) and developed methods for fast gate sensing of double-dot devices relevant for readout of Majorana-based quantum bits.

Using a nanowire transmon, hosting a quantum dot inside the Josephson junction of the transmon, we studied how the spin-orbit coupling allows for direct driving of the spin transition of the quantum dot (arXiv). Moreover, we implemented a novel Andreev spin qubit in the same platform with improved stability and faster operations compared to the only previous implementation of Andreev spin qubits (arXiv).

With a hybrid nanowire embedded into a superconducting resonator, we showed that the kinetic inductance of the nanowire can be controlled by a voltage gate (Phys. Rev. Applied). The architecture that we now understand well could in the future be an excellent platform for magnetic-field-compatible voltage-controlled quantum electronics.

We showed that a low gap superconductor can be used to mitigate qubit loss imposed by quasiparticles being excited by phonons created by high-energy radiation (Phys. Rev. Applied). This work demostrates a path forward to mitigate quasiparticle loss for superconducting qubits as well as topological qubits.
