Quantum communication networks with solid-state nodes and multi-photon entangled states — •Durga Dasari1, Roland Nagy2, Florian Kaiser1, and Joerg Wrachtrup1 — 13.

Quantum Internet is an entangled communication network in which the quantum nodes are connected by entangled connections established by single photons. Optically active solid-state spin registers have demonstrated their unique potential in quantum computing, communication, and sensing. They can be used to realize scalable quantum networks based on establishing entanglement amongst multiple systems via photonic interference. We will present here schemes to realize memory-enhanced quantum networks based on spin-defects in 4H-SiC [1] and diamond [2].
