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?

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

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

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.

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

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

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

There may be unknown particles lurking inside the quantum foam.

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

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

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

Are quantum fields real, or are they simply calculational tools? These 3 experiments show that if energy is real, so are quantum fields.

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

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

Is it like a tiny ball — or what?

Einstein tried to disprove quantum mechanics. Instead, a weird concept called entanglement showed that Einstein was wrong.

The very word "quantum" makes people's imaginations run wild. But chances are you've fallen for at least one of these myths.

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

Experiments tell us quantum entanglement defies space and time.

Realizing that matter and energy are quantized is important, but quantum particles aren't the full story; quantum fields are needed, too.

To Einstein, nature had to be rational. But quantum physics showed us that there was not always a way to make it so.

The central equation of quantum mechanics, the Schrödinger equation, is different from the equations found in classical physics.

Though quantum mechanics is an incredibly successful theory, nobody knows what it means. Scientists now must confront its philosophical implications.

The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer's suggestive simulation.

The quantum world — and its inherent uncertainty — defies our ability to describe it in words.

When you combine the Uncertainty Principle with Einstein's famous equation, you get a mind-blowing result: Particles can come from nothing.

There could be variables beyond the ones we've identified and know how to measure. But they can't get rid of quantum weirdness.
