R. I. Woodward et al., “Simplifying Measurement-Device-Independent Quantum Key Distribution with Directly Modulated Laser Sources,” 2021 Optical Fiber Communications Conference and Exhibition (OFC), 2021, pp. 1-3.
We demonstrate a new MDI-QKD system design employing gain-switched, injection-locked lasers to directly generate GHz-clock-rate encoded states, greatly simplifying MDI-QKD and improving state-of-the-art performance by an order of magnitude.
