Quantum Leaps, Long Assumed to Be Instantaneous, Take Time
An experiment caught a quantum system in the middle of a jump — something the originators of quantum mechanics assumed was impossible.
Physicists Can Finally Peek at Schrödinger's Cat Without Killing It Forever
There may be a way of sneaking a peak at Schrödinger's cat — the famous feline-based thought experiment that describes the mysterious behavior of subatomic particles — without permanently killing the ...
A quantum experiment suggests there’s no such thing as objective reality - MIT Technology Review
Physicists have long suspected that quantum mechanics allows two observers to experience different, conflicting realities. Now they’ve performed the first experiment that proves it.
Pilot Wave Theory and Quantum Realism
There’s one interpretation of the meaning of quantum mechanics that manages to skip a lot of the unphysical weirdness of the mainstream interpretations: it's...
Iodine Molecular Movie
This movie, derived from LCLS data, shows an iodine molecule moving in the first 2 trillionths of a second after being excited by a laser pulse. The clouds o...
We May Have Found a Way to Cheat the Second Law of Thermodynamics
Physicists created a new quantum theorem for entropy, and included is a possible exception.
2016 Nobel Prize In Physics Awarded To David Thouless, Duncan Haldane And Michael Kosterlitz
They were honored for their work in revealing the secrets of exotic matter. Their discoveries, using advanced mathematics, had boosted research in condensed matter physics and raised hopes for uses in...
A New ‘Einstein’ Equation Suggests Wormholes Hold Key To Quantum Gravity
A new Einsteinian equation, ER=EPR, may be the clue physicists need to merge quantum mechanics with general relativity.
China Launches The First Quantum Communications Satellite – And What Is That, Exactly?
Congratulations are in order for China: by launching the world's first quantum communications satellite, the country has achieved an interesting — if..
Schrödinger’s cat just got even weirder (and even more confusing)
The researchers hope their findings will help make quantum computers a reality.
Newborn babies intuitively understand quantum mechanics
Quantum mechanics is notoriously perplexing. But there's one set of humans who innately understand how it works.
The Search For Hidden Dimensions Comes Up Empty Again
Swinging pendulum obeys inverse square law, fails to fall into hidden dimension. Here is the sort of conflict facing physicists: quantum mechanics takes place on the fixed stage of space and time; in ...
Step Inside The Large Hadron Collider (360 video)
A 360 tour of CERN that takes you deep inside the Large Hadron Collider – the world’s greatest physics experiment - with BBC Click’s Spencer Kelly.
Three 'Twisted' Photons In 3 Dimensions
Researchers at the Institute of Quantum Optics and Quantum Information, the University of Vienna, and the Universitat Autonoma de Barcelona have achieved a new milestone in quantum physics: they were ...

A Different Picture Of Quantum Surrealism
With its ideas of particles zipping in and out of existence, quantum mechanics is probably the kookiest-sounding theory in science. And our understanding of it is little helped by the mysterious “pro...

Scattering length
The scattering length in quantum mechanics describes low-energy scattering. It is defined as the following low-energy limit,where is the scattering length, is the wave number, and is the s-wave pha...
Totalitarian principle
In quantum mechanics, Gell-Mann's Totalitarian Principle states: "Everything not forbidden is compulsory." Physicist Murray Gell-Mann borrowed this expression from T.H. White's The Once and Future Ki...

Coincidence counting (physics)
In quantum physics, coincidence counting is used in experiments testing particle non-locality and quantum entanglement. In these experiments two or more particles are created from the same initial pac...
Momentum space
In physics and geometry, there are two intertwined vector spaces.Position space (also real space or coordinate space) is the set of all position vectors r of an object in space (usually 3D). The posit...
