A time-phase BB84 QKD setup with one detector per basis uses the temporal Talbot effect for control-basis measurement, achieving positive but non-secure 'simplistic' key rates that require detection-efficiency balancing to be secure.
Fast single-photon detectors and real-time key distillation enable high secret-key-rate quantum key distribution systems,

High-dimensional quantum key distribution with resource-efficient detection
A time-phase BB84 QKD setup with one detector per basis uses the temporal Talbot effect for control-basis measurement, achieving positive but non-secure 'simplistic' key rates that require detection-efficiency balancing to be secure.
