1. An information processing device comprising:
a semiconductor substrate;
a deep impurity disposed within the semiconductor substrate, the deep impurity having a plurality of spin-selective optical transitions;
an optical structure coupled to the semiconductor substrate and having one or more photonic modes;
a controller configured to manipulate a quantum state of the deep impurity by applying at least one of a magnetic field, an electric field, or a mechanical strain to the semiconductor substrate to cause a subset of the spin-selective optical transitions of the deep impurity to couple to a first one of the photonic modes of the optical structure;
an optical detector; and
a quantum information channel arranged to collect photons from the optical structure and carry the photons to the optical detector, wherein the optical detector is configured to determine the number of photons received from the quantum information channel and infer the quantum state of the deep impurity based on the number of photons.
