  Quantum teleportation is a fundamental ingredient for quantum information
science and technology. In particular, the ability to perform quantum
teleportation between quantum systems of different natures and encoding types
is crucial for building complex systems, such as distributed quantum internet.
Here we propose a scheme to teleport a continuous variable optical qubit,
encoded in an optical qumode by means of a superposed coherent state, onto a
discrete variable solid-state qubit, associated with a single nitrogen-vacancy
center spin in diamond, via a hybrid entanglement. By using a newly developed
method for Bell-state measurement, which relies only on light homodyne
detection and spin polarization measurement, near-deterministic and -perfect
quantum teleportation can be achieved for large coherent-state amplitude input.
Taking noise effects into account, we find that the average teleportation
fidelity can still exceed the classical limit, enabling substantial
teleportation distances under realistic experimental conditions.
