Caltech Demonstrates Multiplexed Entanglement in a Quantum Network

Engineers at Caltech have achieved a significant milestone in quantum communication by demonstrating a quantum network with two nodes, each containing multiple qubits. The team developed a novel protocol for entanglement multiplexing, enabling parallel quantum information transmission using ytterbium atoms embedded in yttrium orthovanadate (YVO4) crystals. This approach overcomes the bottleneck of sequential qubit preparation and photon transmission, significantly boosting communication rates. […]
