Physicist Brian Cox has rarely been shy about his enthusiasm for big, difficult ideas, but his reaction to a recent quantum ...

THE powerful mathematical framework for understanding complex quantum operators is rooted in a field called “quantum harmonic analysis.” That’s a mouthful. These three words lumped in one phrase ...

Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of ...

Katie has a PhD in maths, specializing in the intersection of dynamical systems and number theory. She reports on topics from maths and history to society and animals. Katie has a PhD in maths, ...

Theoretical physicists are trying to understand how the many possibilities that exist in quantum physics can become 'real.' A new model developed by UC Davis researchers suggests that there may be ...

Imagine zooming into matter at the quantum scale, where tiny particles can interact in more than a trillion configurations at once. If that sounds complicated, it is. Physicists often rely on ...

Imagine the tap of a card that bought you a cup of coffee this morning also let a hacker halfway across the world access your bank account and buy themselves whatever they liked. Now imagine it wasn’t ...

Photo of the experimental setup to couple MWs to N- 𝑉⁢s using grape dimers. A stripped optical fiber with N- 𝑉 spins, cantilevered from a rod, lies between two grapes. The grapes were positioned on ...

Quick: what’s 4 + 5? Nine right? Slightly less quick: what’s five plus four? Still nine, right? Okay, let’s wait a few seconds. Bear with me. Feel free to have a quick stretch. Now, without looking, ...

Two hedge fund quants say they have built a machine learning model that—like humans—is able to learn broad ideas from small amounts of data. Kharen Musaelian and Dario Villani, co-founders of ...

Encryption—the process of sending a scrambled message that only the intended recipient’s device can decode—allows private and public sectors alike to safeguard information. Traditional encryption uses ...
