🔴 کوانتوم بیت (Qubit)؛ قلب تپنده‌ی محاسبات فراتر از سیلیکون

🔸 کیوبیت، معادل کوانتومی بیت کلاسیک است اما با رفتاری که قوانین فیزیک کلاسیک را به چالش می‌کشد. برخلاف بیت‌های سنتی که فقط ۰ یا ۱ هستند، کیوبیت‌ها می‌توانند در حالت‌های برهم‌نهی (superposition) و درهم‌تنیدگی (entanglement) قرار بگیرند، که اساس قدرت خارق‌العاده رایانش کوانتومی است.

🔹 در سیستم‌های کوانتومی، کیوبیت‌ها توسط ذراتی چون یون‌های به دام افتاده، فوتون‌ها یا مدارهای ابررسانا ساخته می‌شوند. کنترل این کیوبیت‌ها نیازمند فناوری‌هایی مانند خنک‌سازی تا نزدیک صفر مطلق، پالس‌های لیزری دقیق و طراحی الگوریتم‌های مقاوم در برابر نویز است. الگوریتم‌هایی مانند Shor برای فاکتورگیری اعداد بزرگ یا Grover برای جستجوی سریع در پایگاه داده، بدون وجود کیوبیت‌ها ممکن نبودند. در عین حال، decoherence و خطای کیوبیتی، چالش‌های عمده‌ای در مسیر مقیاس‌پذیری هستند.

⭕️ اگر آینده‌ی امنیت، شبیه‌سازی مولکولی و حل مسائل NP-Complete را می‌خواهیم، باید قلب آن را — یعنی کیوبیت — درک کنیم.

Export WhatsApp stickers to Telegram on iPhone

You can’t. What you can do, though, is use WhatsApp’s and Telegram’s web platforms to transfer stickers. It’s easy, but might take a while.Open WhatsApp in your browser, find a sticker you like in a chat, and right-click on it to save it as an image. The file won’t be a picture, though—it’s a webpage and will have a .webp extension. Don’t be scared, this is the way. Repeat this step to save as many stickers as you want.Then, open Telegram in your browser and go into your Saved messages chat. Just as you’d share a file with a friend, click the Share file button on the bottom left of the chat window (it looks like a dog-eared paper), and select the .webp files you downloaded. Click Open and you’ll see your stickers in your Saved messages chat. This is now your sticker depository. To use them, forward them as you would a message from one chat to the other: by clicking or long-pressing on the sticker, and then choosing Forward.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences.
