Breakthrough in Quantum Entanglement of Light and Sound
Researchers at the Max-Planck-Institute for the Science of Light have developed a method to entangle optical photons with phonons, representing a significant advancement in quantum entanglement. This hybrid entanglement, achieved through Brillouin scattering, allows for stable connections between light and sound particles, even at higher temperatures, and could enhance quantum communication and computing. The study, published in Physical Review Letters, highlights the potential of this technique in various quantum applications.
