With attempts to establish cybersecurity in every aspect of our connected world struggling to succeed, quantum computing may arrive before true information security is established. If such time does occur, an upheaval of current encryption protocols may take place. However, continuing research into device-independent quantum key distribution (DIQKD) protocols is helping build confidence in these theoretical security methods. Independent of the trust placed in the underlying hardware enabling the QKD setup, U.S., Czech, French, and other researchers at Zurich’s Institute of Theoretical Physics have determined DIQKD is possible with quantum technology and protocols presently available. 

Entropy accumulation; it’s a piece to DIQKD.
