New Army-funded research could help lay the groundwork for future quantum communication networks and large-scale quantum computers. Researchers sent entangled qubit states through a communication cable linking one quantum network node to a second node. Scientists at the Pritzker School of Molecular Engineering at the University of Chicago, funded and managed by the U.S. Army Combat Capability Development, known as DEVCOM, Army Research Laboratory s Center for Distributed Quantum Information, also amplified an entangled state via the same cable first by using the cable to entangle two qubits in each of two nodes, then entangling these qubits furt ....
