An atom’s electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied. This fundamental property […]
JILA researchers have tricked nature by tuning a dense quantum gas of atoms to make a congested “Fermi sea,” thus keeping atoms in a high-energy state, or excited, for about 10% longer than usual by […]

What does it mean when we say that something is extremely cold? A physicist’s answer would be: this means that atoms and molecules barely move. For several decades now, physicists have been developing techniques to […]
If you’ve ever had to buy hot dogs for a cookout, you might have found yourself solving a math problem involving least common multiples. Setting aside the age-old question of why hot dogs usually come […]
Copenhagen-based QDevil is developing products right now to accelerate quantum research while positioning itself to provide services and solutions for the emerging quantum industry, according to Jonatan Kutchinsky, CEO and co-founder of the company. “The […]
QWorld welcomes you to participate in our global quantum jam “QJam2021” held online from Friday, Nov 26 to Sunday, Dec 5. QJam2021 is open to students, quantum enthusiasts, researchers, educators, teachers, artists, writers, designers, animators, […]
Quantum 5, 584 (2021). https://doi.org/10.22331/q-2021-11-18-584 I’ve been building Powerpoint-based quantum computers with electron spins in silicon for 20 years. Unfortunately, real-life-based quantum dot quantum computers are harder to implement. Materials, fabrication, and control challenges still […]
By Carolyn Mathas Mark Twain is said to have uttered “History doesn’t repeat itself, but it often rhymes,” we may observe such rhymes when comparing the advent of classical computing and today’s evolving quantum computing. […]
In a recently published article in Physical Review Letters, the ALICE collaboration has used a method called femtoscopy to study the residual interaction between two-quark and three-quark particles. Through this measurement, an interaction between the […]
