Science Education | Quantum's Promise

"Spooky action at a distance", which indeed is very remote in space but not in time, is quantum entanglement, the phenomenon that is at the basis of contemporary scientific research. Researchers are testing this technology to digitize the most reliable method of communication.

Interference means correlation of two quantum states between the particles as if the correlation persisted even in the huge separations. This being done thus can promptly come up with cryptographic private and public key pairing systems with high security levels. The physical principle of interconnected particles can be exploited by scientists to make encrypted keys unsafe even from eavesdropping. This quantum encryption technology, namely quantum key distribution (QKD), provides pinnacle security that no classical encryption scheme could replicate.

Besides that, in this field the practicality of the final product was greatly enhanced by the breakthroughs that have been made in the area of distance entanglement generation and manipulation. Governments and private sector are therefore putting a lot of money on the improvement of the quantum network technologies, which implies that a new kind of safe and personal communication has been born.

As the development of quantum technology continues and the theoretical concept of quantum entanglement becomes a practical tool, hours and days could soon mean nothing when it comes to confidential communication – just because it's possible to mesh separate data streams together securely.
