Two qubits sat half a meter apart, with no direct link between them. Yet correlated microwave photons pushed them into a shared quantum state, offering a new route to entanglement without constant intervention. Distributed entanglement connects quantum bits across separate locations. It could support larger quantum processors and networks that move quantum information between distant modules. Most existing approaches require carefully timed control pulses, repeated measurements or post-selection. The ISTA method instead uses the qubits’ environment as the entangling mechanism. Future quantum computing will require correlations between distant modules. This feature, known as distributed entanglement, has traditionally relied on active control and repeated measurements.
