Top quark and top antiquark entanglement

The CMS experiment has just reported the observation and confirms the existence of #entanglement between the top #quark and its #Antiparticle beyond reasonable doubt.

The CMS experiment has just reported the observation of quantum entanglement between a top quark and a top antiquark, simultaneously produced at the LHC.

In quantum mechanics, a system is said to be entangled if its quantum state cannot be described as a simple superposition of the states of its constituents. If two particles are entangled, we cannot describe one of them independently of the other, even if the particles are separated by a very large distance. When we measure the quantum state of one of the two particles, we instantly know the state of the other. The information is not transmitted via any physical channel; it is encoded in the correlated two-particle system.

Quantum information is a field of physics that was born with the work of John Bell, a CERN physicist, in the mid 1960’s. Soon after, Aspect, Clouser, and other physicists did important pioneering experimental work to test “Bell’s theorem”, and in 2007 Zeilinger’s team convincingly demonstrated the existence of entanglement between two photons, too far away from each other for the information to travel between them at the speed of light. This breakthrough brought Aspect, Clauser, and Zeilinger the 2022 Nobel Prize in Physics, “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science”. Quantum entanglement was mostly examined for states of photons and electrons until 2023, when ATLAS reported the observation of entanglement in the top quark-antiquark system.

As development of large language models (LLM) progresses, aligning them with human preferences has become increasingly important.

A proposed approach to detect Majorana fermions in Kitaev spin liquids by using scanning tunneling microscopy could lead to the unambiguous confirmation of both the spin-liquid state and its Majorana zero modes.

A team of artificial intelligence specialists at Google’s DeepMind has developed an AI-based system called SAFE that can be used to fact check the results of LLMs such as ChatGPT. The group has published a paper describing the new AI system and how well it performed on the arXiv preprint server.

Imagine playing a racing game like Mario Kart, using only your brain to execute the complex series of turns in a lap.

Largely thanks to advances in semiconductor technology, a measure called energy-efficient performance is on track to triple every two years (EEP units are 1/femtojoule-picoseconds).

In particular, the EEP increase will be enabled by the advanced packaging technologies we’ve been discussing here. Additionally, concepts such as system-technology co-optimization (STCO), where the different functional parts of a GPU are separated onto their own chiplets and built using the best performing and most economical technologies for each, will become increasingly critical.

Our brain waves can align when we work and play closely together. The phenomenon, known as interbrain synchrony, suggests that collaboration is biological.

Sam Bankman-Fried was sentenced Thursday to 25 years in prison for his role in defrauding users of the collapsed cryptocurrency exchange FTX. In a Lower Manhattan federal courtroom, U.S. District Judge Lewis Kaplan called the defense’s argument misleading, logically flawed, and speculative.

Bankman-Fried, wearing a beige jailhouse jumpsuit, struck an apologetic tone, saying he had made a series of “selfish” decisions while leading FTX and “threw it all away.”

“It haunts me every day,” he said in his statement.

Prosecutors had sought as much as 50 years, while Bankman-Fried’s legal team argued for no more than 6½ years. He was convicted on seven criminal counts in November and had been held at the Metropolitan Detention Center in Brooklyn since.
