• Resumen

  • Two independent teams have transferred quantum information over several kilometers of fiber optic networks. Establishing teleportation over long distances is a crucial step towards exchanging the quantum cryptographic keys needed for making data sent over such a network secure. The phenomenon involves the quantum states of one particle being transferred to another, distant particle without anything physical traveling between them. It relies on a property called entanglement, in which measuring the state of one particle immediately affects the state of its entangled partner
