Violation of Bell Inequality with Unentangled Photons Violation of local realism via Bell inequality - a profound and counterintuitive manifestation of quantum theory that conflicts with the prediction of local realism - is viewed to be intimately linked...

Violation of Bell's inequality without entanglement. This looks like fascinating work: apparently the inequality can also be violated when quantum particles are simply indistinguishable.

~got bored this afternoon, do forgive me. But on a serious note would love to know who I haven't discovered on here yet (or mistakenly omitted due to the sheer amount of people)

Renormalisation is a central concept in modern physics. It describes how the dynamics of a system change at different scales. A great way to understand and visualise renormalisation is the Ising model

(some math, but one can follow without it )

They appear to be pretty intuitive. Some colleagues were recently starting to hop onto the distributed quantum computing language, and the terms teledata and telegate stuck pretty soon!

A tricky thing about modern society is that no one has any idea when they don’t die.

Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

Consider this a warning. Factoring small numbers is a bad benchmark. Because the key to factoring small numbers isn’t making the quantum computer "work well". That’s the key to factoring *large* numbers. For small numbers it's sufficient to generate a far-too-large circuit, and light the fuse.

This is a science video about quantum 🔊

2025 is NOT the Quantum Year — This is 👇 125 years of quantum physics condensed into a calendar year

Rainy weekend project: condense 125 years of quantum physics into 1!

The "Quantum Year" calendar is interactive.

Feedback welcome.

I just sat down in a chair, and was supported because of trillions of quantum-mechanical interactions between the particles in my butt and the particles in the seat. This lends credence to the notion that quantum computation occurs in many parallel universes, an idea first propo

This is a cool demonstration. You can think about how far the center of the coin has to go: it’s a circle with radius 2r (if r is the radius of the coin). The circumference is therefore 4πr, meaning a coin of circumference 2πr will have to do 2 rotations 🧪

Googles claim that their result "lends credence to the notion that quantum computation occurs in many parallel universes" is nonsense, because their results are perfectly well explained by quantum mechanics independent of how you interpret it.
