How Quantum Pairs Stitch Space-Time
Brian Swingle was a graduate student studying the physics of matter at the Massachusetts Institute of Technology when he decided to take a few classes in string theory to round out his education — “be...
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...
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...
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.
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...
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...
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...
Schrödinger’s cat just got even weirder (and even more confusing)
The researchers hope their findings will help make quantum computers a reality.
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...
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...
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 ...
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..
Quantum "Weeping Angel" Effect Freezes Atoms In Place
The paradox of Schroedinger’s Cat famously demonstrates that a quantum cat sealed in a box is both alive and dead at the same time until we look inside, at which point it becomes one or the other. Suc...
History of physics
Physics (from the Ancient Greek φύσις physis meaning "nature") is the fundamental branch of science that developed out of the study of nature and philosophy known, until around the end of the 19th cen...
