Quantum entanglement, and what it mean for the future of the Internet where information is created, stored and moved around in ways that mirror the bizarre behavior of the quantum world - sending quantum information instead of classical information.

Quantum communication takes advantage of the laws of quantum physics to transport and protect data. Relevant technologies include quantum repeaters, quantum memory, quantum interfaces (transferring qubit states from photons at one wavelength to another, which is necessary for connecting or scaling quantum computers), and quantum key distribution (exchanging cryptographic keys in a quantum state using qubits). Quantum networking has seen significant progress over the past decade with more fundamental breakthroughs expected in the near future. Standards and best practices for reliable and reproducible performance measurement are needed to accelerate progress and enable broad adoption.
