First image of Quantum Entanglement | Einstein's 'spooky' particle action
Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated, interact, or share spatial proximity in ways such that the quantum state of each particle can...
An experiment hints at quantum entanglement inside protons
Particles inside protons seem to be linked on a scale smaller than a trillionth of a millimeter.
Quantum Physics: What Is Really Real?
Ever since they invented quantum theory in the early 1900s, explains Maroney, who is himself a physicist at the University of Oxford, UK, they have been talking about how strange it is — how it allows...
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...
Quantum Computing Is About To Overturn Cybersecurity’s Balance Of Power
Quantum mechanics is now being used to construct a new generation of computers that can solve the most complex scientific problems—and unlock every digital vault in the world. These will perform in s...
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.
Schrödinger’s cat just got even weirder (and even more confusing)
The researchers hope their findings will help make quantum computers a reality.
Quantum Teleportation? Producing Spin-Entangled Electrons
Researchers have successfully produced pairs of spin-entangled electrons and demonstrated that they remain entangled even when they are separated from one another on a chip. This research could contri...
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..
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 ...
Teleportation is Becoming a Reality
While scientists can't help you get to work any faster yet, they are trying to solve the problem through teleportation.
Albert Einstein Wouldn’t Like It: New Test Proves Universe Is ‘Spooky’
The universe really is weird, which is bad news both for Albert Einstein and for would-be hackers hoping to break into quantum encryption systems. Eighty years after the physicist dismissed as “spooky...
Best Teleportation Proof To Date | Police Chase
Circa' Sometime During The 90's
The Race To Prove 'Spooky' Quantum Connection May Have a Winner
Particles don’t obey the same rules as people. Poke a particle, and another one far away can instantly respond the touch -- without any messages passing through the space between, as if the two partic...
Beam Me Up? Teleporting Is Real, Even If Trekkie Transport Isn't
"I have a hard time saying this with a straight face, but I will: You can teleport a single atom from one place to another," says Chris Monroe, a biophysicist at the University of Maryland. His lab's ...
New Method Of Quantum Entanglement Vastly Increases How Much Information Can Be Carried In A Photon
A team of researchers led by UCLA electrical engineers has demonstrated a new way to harness light particles, or photons, that are connected to each other and act in unison no matter how far apart the...
Quantum entanglement
Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independe...
Teleportation
Teleportation, or Teletransportation, is the theoretical transfer of matter or energy from one point to another without traversing the physical space between them. It is a common subject of science fi...
Tachyon
A tachyon /ˈtæki.ɒn/ or tachyonic particle is a hypothetical particle that always moves faster than light. The word comes from the Greek: ταχύ or tachy /ˈtɑːxi/, meaning "swift, quick, fast, rapi...

Quantum information theory
In physics and computer science, quantum information is physical information that is held in the state of a quantum system. Quantum information is the basic entity that is studied in the burgeoning fi...
De Broglie-Bohm theory
The de Broglie–Bohm theory, also known as the pilot-wave theory, Bohmian mechanics, the Bohm or Bohm's interpretation, and the causal interpretation, is an interpretation of quantum theory. In additio...
