Cisco quantum network controller lets apps order entanglement on demand

What happened

Cisco has built a Quantum Network Controller, a research prototype that lets an application ask a quantum network for entanglement and leaves the network to work out the delivery. Entanglement, a linked quantum state shared between distant points, is the resource these networks distribute, and operators today set up the hardware that produces it device by device, link by link. Single quantum processors still hold fewer qubits than the work requires, so more capacity has … More → The post Cisco quantum network controller lets apps order entanglement on demand appeared first on Help Net Security .
