Quantum entanglement among quarks

Quantum entanglement among quarks

Computer scienceParticle physicsQuantum physics

By César Tomé

Collisions of high energy particles produce “jets” – quarks, antiquarks, or gluons moving through the quantum vacuum. Due to the confinement property of strong interactions, quarks are never directly detected but instead fragment into many secondary particles. Scientists have long expected that as jets propagate through the confining quantum vacuum, they will modify that vacuum […]

In probability theory and statistics, a collection of random variables is independent and identically distributed (iid) if each random variable has the same probability distribution as the others and all are mutually independent. Most supervised machine learning methods assume that training and testing or production samples are drawn iid from the same underlying distribution. But […]

Computer scienceMaterialsNanotechnology

By César Tomé

Billions of tiny particles packed into rechargeable lithium-ion battery electrodes are responsible for storing charge and making it available when it’s needed to do work. X-ray movies of this process show the particles absorbing and releasing lithium ions as the battery charges and discharges. Now, in an important step forward, researchers have used a type […]

A novel computer memory design has been created by researchers, offering significant enhancements in performance while simultaneously addressing the pressing need to minimize energy consumption in internet and communications technologies. Projections suggest that these technologies could account for nearly one-third of the world’s electricity consumption within the next decade. A team of researchers has devised […]

Organoid intelligence: brains acting as computers

Organoid intelligence: brains acting as computers

Computer scienceNeuroscience

By Rosa García-Verdugo

While for long in neuroscience, computers were used to model brain function, organoid intelligence, a new scientific field, aims to do the opposite by developing biological computers which would benefit from the efficiency of our most complex biological machine: the brain. Fear not. The objective is not to connect humans by their brains to power […]

Computer scienceMaterialsNanotechnology

By César Tomé

Scientists have successfully demonstrated that autonomous methods can discover new materials. The artificial intelligence (AI)-driven technique led to the discovery of three new nanostructures, including a first-of-its-kind nanoscale “ladder.” The newly discovered structures were formed by a process called self-assembly, in which a material’s molecules organize themselves into unique patterns. Scientists at Brookhaven’s Center for […]

Last year’s Nobel Prize in Physics celebrated the fundamental interest of quantum entanglement, and also envisioned the potential applications in “the second quantum revolution” — a new age when we are able to manipulate the weirdness of quantum mechanics, including quantum superposition and entanglement. A large-scale and fully functional quantum network is the holy grail […]
