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.

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

The evolution of quantum technology is far from over.

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

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

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

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?

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

Can quantum computers do things that standard, classical computers can’t? No. But if they can calculate faster, that’s quantum supremacy.

The perfectly accessible, perfectly knowable Universe of classical physics is gone forever, no matter what interpretation you choose.

Nature may not allow us full access to the weirdness of quantum mechanics.

A relatively new interpretation of quantum mechanics asks us to reimagine the process of science itself.

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

Theoretical physics professor Michio Kaku outlines the evolution of computers from analog to digital and introduces quantum computers as the next frontier.

“You’re not meant to understand what I just said, because I don’t understand what I just said…” Physicist Brian Cox on one of the most complex theories in space science.

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

The combined intellectual heft of multiple “big thinkers” delivered arguably the most successful scientific theory in history.

Some processes, like quantum tunneling, have been shown to occur instantaneously. But the ultimate cosmic speed limit remains unavoidable.

Quantum wormholes are mathematically possible — but might also be physically impossible. Physicist Janna Levin explains Hawking’s famous information paradox.

There may be unknown particles lurking inside the quantum foam.

Perhaps the whole Universe is the result of a vacuum fluctuation, originating from what we could call quantum nothingness. 

From the explosions themselves to their unique and vibrant colors, the fireworks displays we adore require quantum physics.

Is it like a tiny ball — or what?

There’s a quantum limit to how precisely anything can be measured. By squeezing light, LIGO has now surpassed all previous limitations.

Quantum physics is starting to show up in unexpected places. Indeed, it is at work in animals, plants, and our own bodies. 

Within our observable Universe, there’s only one Earth and one “you.” But in a vast multiverse, so much more becomes possible.

Even with quantum teleportation and the existence of entangled quantum states, faster-than-light communication still remains impossible.

Quantum uncertainty and wave-particle duality are big features of quantum physics. But without Pauli’s rule, our Universe wouldn’t exist.

A longstanding mismatch between theory and experiment motivated an exquisite muon measurement. At last, a theoretical solution has arrived.
