Quantum technology promises big things for digital security and computing power, but the very thing it relies upon - quantum entanglement - has so far proven too fickle to reliably control.

A massive project to supercharge the world’s largest particle collider launched on Friday in the hope that the beefed-up machine will reveal fresh insights into the nature of the universe. The 950m Swiss franc (£720m) mission will see heavy equipment, new buildings, access shafts and service tunnels installed, constructed and excavated at the Large Hadron Collider (LHC) at Cern, the particle physics laboratory on the edge of Geneva.

Physicists working at the Large Hadron Collider have made a major new detection of the famous Higgs boson, this time catching details on a rare interaction with one of the heaviest fundamental particles known to physics - the top quark.

There's something strange happening in the universe that is making humanity's most cutting-edge physics experiments contradict one another.

Scientists have produced the firmest evidence yet of so-called sterile neutrinos, mysterious particles that pass through matter without interacting with it at all. The first hints these elusive particles turned up decades ago. But after years of dedicated searches, scientists have been unable to find any other evidence for them, with many experiments contradicting those old results.

The largest particle detector of its kind has failed to turn up any hints of dark matter, despite searching for about a year. Known as XENON1T, the experiment is designed to detect elusive dark matter particles, which are thought to make up most of the matter in the cosmos. Physicists don’t know what dark matter is. One of the most popular explanations is a particle called a WIMP, short for weakly interacting massive particle.

A fracton is a weird imaginary half-particle, and can only move when paired with another fracton. It sounds wild but we could make one in a crystal

We usually think of quantum entanglement in the realm of atomic systems, but now it's been scaled up to relatively massive objects. This opens the door to new kinds of technology.

You haven’t seen headlines recently about the Large Hadron Collider, have you? By Sabine Hossenfelder.

An international team of scientists have provided the first proof of an exotic new state of matter, known as Rydberg polarons.

With their insensitivity to decoherence, Majorana particles could become stable building blocks of quantum computers. The problem is that they only occur under very special circumstances. Now, researchers at Chalmers University of Technology have succeeded in manufacturing a component that is able to host the sought-after particles.

Scientists have just found a way to create a new form of light that could totally change the future of computing and communications. Researchers in a lab at the Massachusetts Institute of Technology were able to link photons and create an entirley new light form that could be used to build light crystals with tremendous scientific applications.

The Large Hadron Collider (LHC) is the particle accelerator that just keeps on giving, and recent experiments at the site suggest we've got the first evidence for a mysterious subatomic quasiparticle that, until now, was only a hypothesis.

Chinese scientists are trying to break their own records by developing a new laser that would be powerful enough to “rip apart empty space” and would simulate even a black hole or a massive star. A team of Chinese physicists working in the Superintense Ultrafast Laser Facility (SULF) in Shanghai has already created the world’s most powerful light pulses. In 2016, these physicists announced success in creating a laser beam generating 5.3 million-billon-watt (or 5.3 petawatts) power. Each pulse generated by the laser lasted for less than one-trillionth of a second.

In the field of particle physics, one of the biggest unresolved mysteries of recent times has been the origin of three different types of so-called "cosmic messenger particles" – some of the highest energy particles in the known universe. While these particles – known as ultrahigh energy cosmic rays, very high energy neutrinos and high energy gamma rays – share common traits, they are distinctly different, meaning scientists have been trying to determine their origins individually.

Updated results from a Japanese neutrino experiment continue to reveal an inconsistency in the way that matter and antimatter behave. From above, you might mistake the hole in the ground for a gigantic elevator shaft. Instead, it leads to an experiment that might reveal why matter didn’t disappear in a puff of radiation shortly after the Big Bang.

Quantum particles "tag" their environment as they move, which can be tracked without the particles being observed directly. In a major scientific breakthrough, researchers at the University of Cambridge have discovered a way to track the "secret movements" of quantum particles when they are not being observed – a concept which was previously thought to be impossible.

For the first time, scientists have witnessed lightning triggering nuclear reactions in the atmosphere, confirming a hypothesis dating back almost a century.
