What Happened
Quantum entanglement allows multiple particles to remain connected regardless of the distance between them. A change in the state of one particle instantly affects the state of others, making this effect a cornerstone for future quantum networks and the quantum internet.
Previously, scientists demonstrated entanglement between two remote quantum nodes and even three-node networks on other physical platforms. However, this is the first time such a result has been achieved with individual atomic qubits, which can be independently controlled, read, and scaled for building computational systems. From . . .

In June, Colt Technology Services and Ciena successfully tested data transmission with quantum-resistant encryption between New York and London.
