זוהו תצורות מקור SPDC המנתקות את דרגות החופש המרחביות והספקטרליות, המאפשרות יצירת זוגות פוטונים משולבים ב-OAM בטוהר גבוה ללא סינון עם אובדן — ממופות על פני סדר OAM, אורך הגביש ורוחב קרן, לשם יישום סקלבילי בעיבוד מידע קוונטי פוטוני.

공간 및 스펙트럼 자유도를 분리하는 SPDC 소스 구성을 식별하여, 손실이 있는 필터링 없이 고순도 OAM 얽힘 광자 쌍을 생성할 수 있음을 확인하였습니다. 이는 확장 가능한 광자 기반 양자 정보 기술(QIT)을 위해 OAM 차수, 결정 길이 및 빔 허리 전반에 걸쳐 매핑되었습니다.

空間自由度とスペクトル自由度を分離するSPDCソース構成を特定し、損失の多いフィルタリングを必要とせずに高純度のOAMエンタングル光子対を生成することを可能にした。スケーラブルな光子量子情報技術に向け、OAM次数、結晶長、ビームウェストにわたるマッピングを実施した。

SPDC source configurations were identified that decouple spatial and spectral degrees of freedom, enabling high-purity OAM-entangled photon pairs without lossy filtering—mapped across OAM order, crystal length, and beam waist for scalable photonic QIT.

אפיון מרחבי וספקטרלי ראשון של זוגות פוטונים מסוג SPDC במהוד ננו-מעגלי (bullseye) מ-LiNbO₃. קצב ספירת זוגות שיא של 0.45 הרץ/מיליוואט, שאומת באמצעות מסגרת מצבים-קוואזי-נורמליים, המאפשרת תכנון חיזויי של מקורות אור קוונטיים בסקאלת הננו.

أول توصيف مكاني وطيفي لأزواج فوتونات SPDC في رنان نانوي دائري من نيوبات الليثيوم (LiNbO₃). تم التحقق من معدل عدّ أزواج قياسي بلغ 0.45 هرتز/ميلي واط باستخدام إطار الأنماط شبه الطبيعية، مما يُتيح التصميم التنبؤي لمصادر الضوء الكمومي على المقياس النانوي.
