Quantum entanglement makes quantum communication even more secure
Quantum devices don’t have to be perfectly understood to be snoop-proof, three studies show

Quantum entanglement, a type of ethereal link between particles, improves the security of quantum communication, as demonstrated in three experiments (the one pictured, by researchers in France, Switzerland and England, used strontium ions in its test).
