چکیده
مرکز نیتروژن-جای خالی یک نقص نقطه ای در الماس است که متشکل از یک جفت همسایه از اتم نیتروژن (که جایگزین یکی از اتم های کربن شده است) و یک جای خالی شبکه می‌باشد. این سامانه یکی از کاندیداهای اصلی جهت تحقق عملی پردازش های کوانتومی است. در این مقاله کاربرد چنین سامانه ای در فرآیند برآورد کوانتومی مورد بررسی قرار خواهد گرفت. مخصوصا برآورد فاز اولیه که می تواند اطلاعات مهمی را در خود کد کرده باشد دقیقا بررسی خواهد شد. به علاوه، تاثیر درهمتنیدگی سامانه با محیط و هم چنین وفاداری حالت تحول یافته نسبت به حالت اولیه را بر دقت برآورد فاز مطالعه خواهیم نمود.
