MDI-QKD Is a Transition Technology and a Logical Next Step on the Path From QKD to a Quantum Internet…

…Currently, QKD works on a point-to-point basis. You have a sender (called Alice, in industry parlance) and a receiver, called Bob. Alice and Bob can securely share QKD-encrypted information with each other via a fiber optic network over a limited distance…

…But now, as researchers begin to accelerate their time to market for quantum solutions, many are concluding that a closed point-to-point network won’t generate a lot of traction…

…Instead, they’re looking at a different use of QKD to create more viable networking opportunities. This is MDI-QKD, or measurement-device independent QKD. (For more technical information, here are two primers for MDI and MDI-QKD)…
