ENTANGLEMENT MANIPULATION

The new research — released on July 2, 2025 in Physical Review Letters—deepens understanding of entanglement's basic properties and provides critical fundamental insight into how to efficiently manipulate entanglement and other in practice.

Entanglement is arguably the central feature of quantum mechanics. 

If two microscopic particles are said to be entangled, then if someone measures a quantum property of one of the particles and then repeats the measurement on its entangled partner, they will always find that the pair is correlated, even when the two particles are separated by vast distances.

Therefore, knowing the state of one particle automatically provides information about the other.

Quantum equivalent of thermodynamics' second law discovered for entanglement manipulation

 

Entanglement battery powers quantum reversibility 

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum world. This second law of entanglement manipulation proves that, just like heat or energy in an idealized thermodynamics regime, entanglement can be reversibly manipulated, a statement which until now had been heavily contested.

Young children outperform state-of-the-art AI in visual object recognition

As artificial intelligence (AI) rapidly grows—a recent UN Trade and Development report projects the global AI market soaring to $4.8 trillion by 2033—the technology seems equipped to handle any task. Driving cars. Analyzing ...

Gene for enzyme in saliva associated with type 2 diabetes

Nutrition scientists have been working to understand the relationship between type 2 diabetes and genes that express a salivary enzyme that breaks down starch, but many conflicting studies have led to few clear answers.

Clinical test predicts best rheumatoid arthritis treatment on first try

1 in 100 people in Britain today live with rheumatoid arthritis (RA). Unlike osteoarthritis (OA), RA is caused not by wear and tear but by the body's immune system attacking its own joints. RA can strike quickly at any age—but ...
