Most quantum communication tasks need to rely on the transmission of quantum signals over long distances. Unfortunately, transmission of such signals is most often limited by losses in the channel, the same issue that affects classical communication. Simple signal amplification provides an elegant solution for the classical world, but this is not possible in the quantum world, as the no-cloning theorem...
Quantum networking is a requirement for distributed quantum computation and any potential future quantum internet. Due to the no-cloning theorem, noiseless amplification is not possible and so a different technique is needed to extend the communication range. Quantum repeaters are a device that distributes entanglement over long distances. This entanglement can then be used to teleport information...
We present a simple design of a quantum repeater design build from single NV- centers embedded in an optical cavity. We compare different quantum networks from a simple linear chain to a fully fault-tolerant quantum internet.
