Quantum physics is an unnecessary complication, researchers say

To this day, researchers don’t fully understand quantum physics. But in a new paper, physicists from MIT say that that’s okay – because the phenomena we use quantum physics to expl...

Physicists discover quantum particles that break the rules of reality

Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to belong to one of two categories — bosons or fermions — bu...

Physicists discover quantum particles that break the rules of reality 

Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to belong to one of two categories — bosons or fermio...

Quantum ‘Jamming’ Could Help Unlock the Mysteries of Causality

To keep communications secure in a post-quantum world, cryptographers are digging down into the concept of cause and effect.

Swirling Vortex in Water Tank Reveals Hidden Geometry of Quantum World

The tank itself is unremarkable. A metre wide, two metres long, five centimetres deep, filled with ordinary water in a lab in Okinawa. Beneath it, a light tablet glows. Above it, a...

How Quantum Mechanics Went From Baffling Theory to Revolutionizing Modern Technology

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research. A century ago, quantum mechanics was a bold and puzzling...

Collisional quantum gates created using fermionic atoms

Architectures could support quantum-chemistry simulations The post Collisional quantum gates created using fermionic atoms appeared first on Physics World.

Researchers Capture Quantum Interference in One of Nature’s Rarest Atoms

Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom. A defining insight that sets quantum physics apart from...

An unorthodox version of quantum theory could reveal what reality is

The implications of quantum mechanics suggest reality isn't as solid as we think it is, but physicist David Bohm had a spin on the theory that restores reality. Columnist Karmela P...

Quantum Reality Gets Stranger: Physicists Put a Lump of Metal in Two Places at Once

Researchers have shown that surprisingly large metal particles can behave according to quantum mechanics, existing in multiple states at once. Can a tiny piece of metal exist in a...

Physicists just found a tiny flaw in time itself

Physicists are rethinking one of quantum mechanics’ biggest puzzles: how fuzzy possibilities become definite reality. New research suggests that spontaneous “collapse” processes—po...

A Physics Trick Could Make Quantum Computers Far Cheaper to Build

Exploring Quantum Computing: Current Practices, Theoretical Underpinnings, and Future Directions

Quantum computing challenges our old assumptions about what machines can and cannot do. How will it transform intelligence, security, and creativity in ways we are only beginning t...

QBox theory may offer glimpse of reality deeper than quantum realm

Physicists have long suspected that there is a layer of physical reality beneath quantum theory and a new mathematical model unveils just how strange it might be

From the Web (FTW) #37: Quantum mechanics and Indian politics: Can physics fill in for psephology

Any student made to slog through physics and keep at least an eye and ear while fantasising about the hottie in the opposite class would recollect the groan-inducing history of qua...

Searching for a quantum advantage in strong-field quantum electrodynamics

Physicists are using quantum computers to simulate high-intensity electromagnetic interactions to test the limits of light and matter under extreme conditions.

Physicists Propose Strange Experiment Where Time Goes Quantum

Cutting-edge atomic clocks may soon reveal a strange possibility: time itself behaving like a quantum object, existing in multiple states at once. Few ideas in physics feel as intu...

What is Quantum Entanglement?

Insider Brief In 1935, Albert Einstein looked at what quantum mechanics was claiming about reality and called it “spooky action at a distance.” He said this as an insult. Decades o...

Scientists put a tiny lump of metal in two places at once in record-breaking quantum experiment

Scientists have pulled off a mind-bending quantum experiment that sounds almost impossible: they showed that tiny metal particles made of thousands of atoms can exist in multiple p...

Physicists Observe Matter in Two Places at Once in Mind-Bending Quantum Experiment

ANU researchers show that atoms can exhibit quantum entanglement, advancing efforts to unify physics. Quantum physicists at the Australian National University (ANU) have achieved a...

Electrons in moiré crystals explore higher-dimensional quantum worlds

The electrons that power our society flow left and right through the circuitry in our electronics, back and forth along the transmission lines that make up our power grid, and up a...

New Teaching Approach Could Open The Door to Quantum Computing

Insider Brief PRESS RELEASE — Quantum computing, an emergent technology with the potential to solve otherwise impossible problems, grew out of quantum mechanics, the branch of phys...

Einstein's Theory Has a Problem -- This Idea Solves It

Physicists have been trying to reconcile the differences between Einstein’s theory of spacetime and our observations of quantum mechanics for almost a century. One way that they’ve...

A real quantum leap
