Quantum physics just pulled off a rewind trick that sounds like sci-fi. Here’s what the experiment actually did—and why it ...

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

The operation of quantum computers, systems that process information leveraging quantum mechanical effects, relies on the ...

Quantum entanglement, the invisible connection between particles that entwines them in such a way that they act as one, has ...

An exotic phase of matter has been realized on a quantum processor. Matter can exist in different forms, or phases, such as liquid water or solid ice. These phases are usually understood under ...

The world of quantum physics is already mysterious, but what happens when that strange realm of subatomic particles is put ...

While we're far away from beaming around like 'Star Trek,' innovation of communications technology has become the closest ...

When we observe the world at our scale, everything seems to obey predictable laws, those of classical physics. But when ...

A century ago, a group of scientists in Europe began developing a theory to explain how the world’s smallest particles interact. Their discoveries underpinned a new branch of physics and laid the ...

The mere mention of “quantum consciousness” makes most physicists cringe, as the phrase seems to evoke the vague, insipid musings of a New Age guru. But if a new hypothesis proves to be correct, ...
