In one implementation, the system includes a direct current (“DC”) current source, a configurable pulse generator, an electronic controller, and a laser diode. The electronic controller is configured to control the DC current source to apply a bias signal to a node. The electronic controller is further configured to control the configurable pulse generator to apply Glauber-state excitation current pulses to the node to generate Glauber-state current injection pulses. The electronic controller is also configured to control the configurable pulse generator to apply decoy-state excitation current pulses to the node to generate decoy-state current injection pulses. An amplitude of the decoy-state current injection pulses is less than an amplitude of the Glauber-state current injection pulses. The laser diode is configured to generate Glauber-state and decoy-state optical signals based on the Glauber-state and decoy-state current injection pulses."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Current injection based generation of indistinguishable Glauber-state and decoy-state optical signals","description":"Systems and methods for generating indistinguishable Glauber-state and decoy-state optical signals.
