دانشمندان توانستند در شرایط آزمایشگاهی «سردترین» دمای ممکن را ایجاد کنند
صفر مطلق، نقطهای است که در آن ذرات بنیادی طبیعت دارای کمترین حرکت ارتعاشی هستند. با این حال هنوز دانشمندان نتوانستهاند دمای صفر مطلق را حتی در شرایط آزمایشگاهی ایجاد کنند.

Quantum information theorists produce new 'understanding' of quantum mechanics
Richard Feynman famously said, "I think I can safely say that nobody understands quantum mechanics." Since Feynman won a Nobel Prize in physics for his work in quantum theory, he certainly understood ...

Reality is just a quantum wave function
<p><em>Most interpretations of quantum mechanics have taken non-locality – “spooky action at a distance” – as a brute fact about the way the world is. But there is another way. Take seriously quantum theory’s higher-dimensional models, and we could make sense…

Scientists calculate absolute quantum speed limit for electronics
It often feels like electronics will continue to get faster forever, but at some point the laws of physics will intervene to put a stop to that. Now scientists have calculated the ultimate speed limit – the point at which quantum mechanics prevents microchips…

Record-setting quantum entanglement connects two atoms across 20 miles
Researchers in Germany have demonstrated quantum entanglement of two atoms separated by 33 km (20.5 miles) of fiber optics. This is a record distance for this kind of communication and marks a breakthrough towards a fast and secure quantum internet.

برندگان نوبل فیزیک ۲۰۲۲ مشخص شدند جایزه نوبل فیزیک ۲۰۲۲ به آلن اسپه، جان اف کلاسر و آنتون زایلینگر برای انجام آزمایشها با فوتونهای درهمتنیده، اثبات نقض نامساویهای بل و علم اطلاعات کوانتومی پیشگامانه اعطا شد.
رساله دکترا و پروژه ارشد اینجانب هر دو اختصاص داشتند به نامساویهای بل، آزمایشهای تجربی مرتبط و نقض موضعیت (locality). سال ۲۰۰۲ با زایلینگر در ایتالیا دیدار داشتم و به او گفتم در حال نوشتن مقالهای در نقد تفسیر کوانتومی او هستم. درباره مفهوم واقعیت فیزیکی که او منکر آن بود با وی بحث کردم. پس از آن تاکنون دو سه مقاله در مورد فلسفه کوانتومی که زایلینگر ارائه کرده است منتشر کردهایم.
خوشحالم که در بیست سال اخیر، بیپشتوانه کافی و تنها با همکاری و اشتیاق دانشجویانم در دانشکده شیمی دانشگاه صنعتی شریف، حوزه بنیادی کوانتوم را در ایران پیش بردهام. حوزهای که اینک، شاید هم بسیار دیر، نوبل فیزیک به سه نفر از پیشگامان و فعالان آن اعطا شده است.

Does consciousness change the rules of quantum mechanics?
Maybe our understanding of quantum entanglement is incomplete, or maybe there is something fundamentally unique about consciousness.

Why the laws of physics don't actually exist
What we call laws of physics are often just mathematical denoscriptions of some part of nature. Ultimate physical laws probably don't exist and physics is all the better for it, says theoretical physicist Sankar Das Sarma

Why 21 cm is our Universe's "magic length"
Photons come in every wavelength you can imagine. But one particular quantum transition makes light at precisely 21 cm, and it's magical.
