  While the manipulation of quantum systems is significantly developed so far,
achieving a single-source multi-use system for quantum-information processing
and networks is still challenging. A virtual state, a so-called ``dressed
state," is a potential host for quantum hybridizations of quantum physical
systems with various operational ranges. We present an experimental
demonstration of a dressed state generated by two-photon magnetic resonances
using a single spin in a single nitrogen-vacancy center in diamond. The
two-photon magnetic resonances occur under the application of microwave and
radio-frequency fields, with different operational ranges. The experimental
results reveal the behavior of two-photon magnetic transitions in a single
defect spin in a solid, thus presenting new potential quantum and
semi-classical hybrid systems with different operational ranges using
superconductivity and spintronics devices.
