Two-dimensional arrays of solid-state quantum memories

Long-distance quantum communication relies on quantum repeaters to overcome the limitations of signal loss and decoherence. In quantum networks with repeater architecture, the distance nodes are entangled through entanglement swapping which is heralded using a classical signal. However, the entangle...
