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 ...

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 ...

Physicists successfully teleport quantum information between photons from different sources, a key step towards a secure ...

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 ...

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 ...

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, ...

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 ...
