For most quantum internet protocols, such as quantum key distribution in quantum cryptography, it is sufficient if these processors are capable of preparing and measuring only a single qubit at a time. Most applications of a quantum internet require only very modest quantum processors.
A quantum internet supports many applications, which derive their power from the fact that by creating quantum entangled qubits, information can be transmitted between the remote quantum processors. This way, local quantum networks can be intra connected into a quantum internet. In the realm of quantum communication, one wants to send qubits from one quantum processor to another over long distances. Currently quantum processors are only separated by short distances. Like classical computing, this system is scalable by adding more and more quantum computers to the network. This is analogous to connecting several classical computers to form a computer cluster in classical computing. Less powerful computers can be linked in this way to create one more powerful processor. Doing this creates a quantum computing cluster and therefore creates more computing potential. Networked quantum computing or distributed quantum computing works by linking multiple quantum processors through a quantum network by sending qubits in-between them. 2.4 Concurrence Percolation in Quantum Networksīasics Quantum networks for computation.2.2 Communication lines: physical layer.
