"high degree of entanglement and high efficiency (65X more) for quantum key distribution or quantum repeaters, by embedding semiconductor quantum dots into nanowire... excited with lasers generating entangled pairs on command... overcame fine structure splitting that caused entangled state to oscillate over time, by taking timestamp of entangled state at each point during oscillations, confirming perfect entanglement... succeeded simulating quantum key distribution... secure quantum communications"
