University research at TU Delft, Netherlands, has laid out a broad roadmap for a quantum internet.  The plan develops the quantum network around two concepts presently unknown to the current internet: (1) Entanglement’s synchronization capability between distant locations; and,  (2) entanglement’s inherent security, considered unbreakable. Engineering, computer science, and physics, all must come into agreement and collaborate closely to enable the increasing functionality of each stage.

As put forth by TUDelft, the six stages toward a quantum computing network, in increasing functionality are:

Stage 1: Trusted repeater development (Ex: Quantum key distribution, or QKD)

Stage 2: Prepare & Measure (Ex: QKD, secure delivery of quantum bits between any two network nodes)

Stage 3: Entanglement generation (Ex: Device independent protocols)

Stage 4: Quantum Memory

Stage 5: Few Qubit Fault Tolerant (Ex: Clock synchronization, distributed quantum computation)

Stage 6: Quantum computing (Ex: Complex chemical modeling; financial market prediction)

“The first true quantum networks, allowing the end-to-end transmission of quantum bits, are expected to be realized in the coming years, heralding the dawn of a large-scale quantum internet.”
