By improving quantum error correction, quantum computations are now faster than ever. But parallel universes? That’s utter nonsense here.

Discover how Quantum Bayesianism challenges traditional quantum mechanics by focusing on the role of the observer in creating quantum reality.

Quantum computing brings significant opportunities — but equally significant cybersecurity risks.

Over a century after we first unlocked the secrets of the quantum universe, people find it more puzzling than ever. Can we make sense of it?

Our classical intuition is no good in a quantum Universe. To make sense of it, we need to learn, and apply, an entirely novel set of rules.

LHC scientists just showed that spooky quantum entanglement applies to the highest-energy, shortest-lived particles of all: top quarks.

No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?

“Quantum mechanics and quantum entanglement are becoming very real. We’re beginning to be able to access this tremendously complicated configuration space to do useful things.”

Do we actually live in a deterministic Universe, despite quantum physics? An alternative, non-spooky interpretation has now been ruled out.

Empty space itself, the quantum vacuum, could be in either a true, stable state or a false, unstable state. Our fate depends on the answer.

The evolution of quantum technology is far from over.

Despite no experimental evidence showing that gravitons exist, they remain a respectable concept in the world of professional physicists.

Electromagnetism, both nuclear forces, and even the Higgs force are mediated by known bosons. What about gravity? Does it require gravitons?

No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?

If atoms are mostly empty space, then why can’t two objects made of atoms simply pass through each other? Quantum physics explains why.

There are limits to where physics makes meaningful predictions: beyond the Planck length, time, or energy. Here’s why we can’t go further.

If all massive objects emit Hawking radiation, not just black holes alone, then everything is unstable, even the Universe. Can that be true?

Often viewed as a purely theoretical, calculational tool only, direct observation of the Lamb Shift proved their very real existence.

If it weren’t for the intricate rules of quantum physics, we wouldn’t have formed neutral atoms “only” ~380,000 years after the Big Bang.

Explore how QBism reframes science by placing the observer at the heart of quantum reality.

Here in our Universe, time passes at a fixed rate for all observers: one second-per-second. Before the Big Bang, things were very different.

Photons come in every wavelength you can imagine. But one particular quantum transition makes light at precisely 21 cm, and it’s magical.

Despite the Sun’s high core temperatures, atomic nuclei repel each other too strongly to fuse together. Good thing for quantum physics!

Here in the 21st century, quantum computing is quickly going from a dream to a reality. But what’s hype, and what’s actually true?

The Multiverse isn’t just a staple of science fiction; there’s real-life science behind it, too. Here are 10 facts to expand your mind.

The electromagnetic force can be attractive, repulsive, or “bendy,” but is always mediated by the photon. How does one particle do it all?

“We don’t have enough knowledge to precisely calculate what is going to happen, and so we assign probabilities to it, which reflects our ignorance of the situation.”

A recent paper in the journal Physical Review Letters claims to prove that a “kugelblitz” is not possible.

For generations, physicists have been searching for a quantum theory of gravity. But what if gravity isn’t actually quantum at all?

It’s possible to remove all forms of matter, radiation, and curvature from space. When you do, dark energy still remains. Is this mandatory?
