⬡Hybrid Qubit Architectures

An electron can occupy a coherent superposition of two dots.

A microwave photon can mediate distant spin interactions.

A semiconductor coupled to a superconductor acquires pairing correlations.

Coherent electron–hole reflection forms subgap states.

Spinful Andreev levels can encode a qubit.

A spin qubit may interface with a superconducting circuit mode.

Strain and phonons provide another quantum information channel.

Optical photons can carry quantum information over long distances.

Optically active semiconductor dots can generate nonclassical light.
