We theoretically propose a new way to realize qubits: a hybrid qubit system consisting of the quantized vertical motion (Rydberg states) and the spin states of electrons on the surface of liquid helium.

Hole-spin qubits in quasi-one-dimensional structures are a promising platform for quantum information processing because of the strong spin-orbit interaction (SOI). We present analytical results and discuss device designs that optimize the SOI in Ge semiconductors.
We propose a minimal design modification of Ge planar quantum dot devices that enhances the spin-orbit interaction by orders of magnitude and enables low power ultrafast hole-spin qubit operations.
Protocol for the deterministic generation of entanglement between two ensembles of nuclear spins surrounding two distant quantum dots.
Versatile set of quantum gates between qubits of a spin quantum computer node.
Perspectives article in Applied Physics Letters special topic Hybrid Quantum Devices. We summarize recent progress and theoretical models that describe superconducting-semiconducting hybrid quantum systems, explain the limitations of these systems, and describe different directions where future experiments and theory are headed.
The flopping-mode configuration enables low-power spin control in quantum dot arrays.
The flopping-mode spin qubit can be efficiently controlled and protected from charge fluctuations.
Performance of single-electron spin qubits in DQDs with respect to dispersive long-distance two-qubit gates mediated by virtual cavity photons.
First demonstration of strong coupling between a single spin in silicon and a single microwave-frequency photon.
