- Abstract: We explore the possibility of the formation of photon-phonon entangled states
in nanoscale wires by exploiting stimulated inter-modal Brillouin scattering of
co-propagating photons that belong to distinct spatial optical modes. Inside
nanowires, the photon-phonon coupling is significantly enhanced owing to
radiation pressure. The Stokes and anti-Stokes processes are decoupled as they
involve different phonon modes that lead to symmetry breaking, which results
from different phase-matching requirements. For the Stokes process
photon-phonon pairs are annihilated or created, in the presence of a classical
pump field, and for the anti-Stokes process we obtain coherent oscillations
between photons and phonons. The appearance of entangled states can extend the
use of nanowires, for example, those made of silicon, into quantum information
processing involving photons and phonons in a setup that can be easily
integrated into an on-chip network.

We identify a strategy for reaching near-unity photon indistinguishability and also discover an interesting phonon-dressing of the exciton-cavity polaritons in the high-Q regime.
