Phân phối trạng thái liên kết phân cực đa photon với độ trung thực đơn vị qua các kênh nhiễu tập thể tùy ý
Tóm tắt
Xét đến nhiễu tập thể, một giao thức khả thi để phân phối trạng thái liên kết phân cực đa photon được trình bày với sự hỗ trợ của bậc tự do không gian. Các thành phần của bộ phân cách chùm ánh sáng phân cực và tấm một nửa sóng có góc nghiêng $$\pi /4$$ hoạt động như các cổng NOT chuyển đổi các chế độ liên kết giữa bậc tự do phân cực và bậc tự do không gian. Các yếu tố quang học phù hợp và hiện có được áp dụng, qua đó giao thức có thể được thực hiện một cách khả thi mà không bị ảnh hưởng bởi nhiễu tập thể tùy ý. Hơn nữa, xác suất thành công của việc phân phối trạng thái liên kết bằng một mô hình nhiễu tập thể đơn vị đạt giá trị bằng đơn vị.
