However\, quan tum dots (QD) often inherently\npossess a fine structure splitting (FSS). Since the entangled photonic\nstate in the presence of non-zero FSS is osc illating\, one must settle\nfor a lower efficiency source through temporal post-selection or a\nlower measured entanglement fidelity. In both cases\ , the overall key\nrate is reduced. Our QKD analysis shows that this trade -off can be\novercome by constructing a time-resolved QKD protocol where a ll photon\npairs emitted by a QD with non-zero FSS can be used in secret k ey\ngeneration. This protocol works only when the detection system's\ntemp oral resolution is much smaller than the FSS period. By\nimplementing our protocol\, higher key rates can be achieved as\ncompared to previous QKD e xperiments with QD entangled photon pair\nsources.\n\n \n\nADD EVENT TO C ALENDAR\n\nApple []  Goog le\n[]  Office 365\n[htt ps://]  Outlook\n[https://www]\n[https://www.addev]  Yahoo\n[ vent/en18189052+yahoo]  \n DTSTAMP:20231201T030113Z END:VEVENT END:VCALENDAR
