A 'beyond-quantum' equivalence principle for superposition and entanglement
The physics of the microrealm involves two famous and bizarre concepts: The first is that prior to observation, it is impossible to know with certainty the outcome of a measurement on a particle; rather ...

Quantum mechanics could explain why DNA can spontaneously mutate
The molecules of life, DNA, replicate with astounding precision, yet this process is not immune to mistakes and can lead to mutations. Using sophisticated computer modeling, a team of physicists and chemists ...
آگاهی چیست و چه میکند؟ چگونه تحریک الکتریکی میلیونها سلول کوچک مغز موجب میشود که ما جهان را تجربه کنیم؟ آگاهی که آخرین راز بزرگ علم نامیده میشود اکنون موضوع بحثهای داغ است و تحولات هیجانانگیزی که در حوزۀ شناخت مغز صورت گرفته است میدان را به روی زیستشناسان، عصب پژوهان، روان شناسان و نیز فیلسوفان گشوده است. آیا ما اختیار یا ارادۀ آگاهانه داریم؟

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.

Canonical Density Matrices from Eigenstates of Mixed Systems
One key issue of the foundation of statistical mechanics is the emergence of equilibrium ensembles in isolated and closed quantum systems. Recently, it was predicted that in the thermodynamic (N→∞) limit of large quantum many-body systems, canonical density…
