Quantum encryption could be used for voice calls

Scientists have developed a quantum encryption key distribution system which could bring its speed up to that of standard encryption methods.

Quantum encryption uses data encoded into photons using a laser and is lauded as an “unhackable” encryption method.

Researchers have discovered a way to encode two bits into a photon by manipulating the release time of the particle and using high-speed photon detectors.

If the technology is implemented, quantum encryption could be used to secure data transfers and voice calls.

Quantum encryption remains a developing field, with the hardware required large and expensive.
