Quantum Entanglement: Spooky Steps to Quantum Networking
Zeeya Merali writes on NewScientistTech:
Even if quantum computers can be made to work, there will still be two big obstacles preventing quantum networks becoming a reality. First, quantum bits, or qubits, stored in matter will have to be transferred to photons to be transmitted over long distances. Secondly, errors that creep in during transmission have to be corrected. Two unrelated studies have now shown how to clear these hurdles.More here.
Both studies use quantum entanglement, a spooky property that links particles however far apart they are. Measuring a quantum property on one particle immediately affects the other, and this effect can be used to “teleport” information between pairs of entangled particles.
