Bristol physicists working to bring quantum cryptology to our phones

It's no secret that our phones are often vulnerable to the occasional malicious hack, no matter how much we believe our passwords to be secure. But what if the encryption methods we used were based on the laws of physics instead of just mathematical formulas? The answer might just lie in quantum cryptology or quantum key distribution, which uses photon modification to encode and transmit data. However, the technology has typically required gear only found in top laboratories. Both sender and rec...
