A team of quantum physicists has taken a concept that once lived purely in equations and turned it into hardware reality, ...

Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

An illustration conveying the idea of a space-based quantum internet, which would seem, like the hypothetical particle of a tachyon, to outpace light. An illustration ...

"These single atoms are like the smallest slits you could possibly build." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. For over 100 years, ...

Entanglement is perhaps one of the most confusing aspects of quantum mechanics. On its surface, entanglement allows particles to communicate over vast distances instantly, apparently violating the ...

The tachyon particle has an almost mythical air about it in the scientific community, mostly because we don’t know if it actually exists. But if it does, the tachyon has some tantalizing connections ...

Discover the fascinating world of particle physics — the most fundamental building blocks of the universe and the forces that connect them. When you purchase through links on our site, we may earn an ...

The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...
