Device-independent quantum key distribution In traditional QKD, the quantum devices used must be perfectly calibrated, trustworthy, and working exactly as they are expected to. Deviations from expected measurements can be extremely hard to detect, which leaves the entire system vulnerable. A new protocol called device independent QKD (DIQKD) or measurement device independent QKD (MDIQKD) allows for the use of uncharacterized or untrusted devices, and for deviations from expected measurements to be included in the overall system. These deviations will cause the protocol to abort when detected, rather than resulting in incorrect data.
