هو طريقة لتوزيع ومشاركة المفاتيح السرية الضرورية في بروتوكولات التشفير وذلك بالاعتماد على خصائص ميكانيك الكم. وتكمن أهميتها في ضمان الحفاظ على سرية المفاتيح بين أطراف الاتصال. ويتضمن توزيع المفاتيح الكمومية QKD إرسال بيانات مشفرة على شكل بتات كلاسيكية عبر شبكات الاتصال، في حين أن المفاتيح اللازمة لفك تشفير المعلومات يتم تشفيرها ونقلها في حالة كمومية باستخدام الكيوبتات.
