Just seven photons can act like billions

Just seven photons can act like billions

A system made of just a handful of particles acts just like larger systems, allowing scientists to study quantum behavior more easily. Most substances physicists...

Gravitational waves provide dose of reality about extra dimensions

While last year’s discovery of gravitational waves from colliding neutron stars was Earth-shaking, it won’t add extra dimensions to our understanding of the universe—not...

Physicists save gravity theory from death

An international group of astronomers, including physicists at the University of St Andrews, has revived a previously debunked theory of gravity, arguing that motions...

Magnetic waves create chaos in star-forming clouds

New research by Stella Offner finds that magnetic waves are an important factor driving the process of star formation within the enormous clouds that...
Scientists discover a 'tuneable' novel quantum state of matter

Scientists discover a ‘tuneable’ novel quantum state of matter

Quantum particles can be difficult to characterize, and almost impossible to control if they strongly interact with each other -- until now. An international team...

Scientists create pristine quantum light source at the edge of silicon chip

The smallest amount of light you can have is one photon, so dim that it's pretty much invisible to humans. While imperceptible, these tiny blips...
Scientists 'teleport' a quantum gate for quantum computers

Scientists ‘teleport’ a quantum gate for quantum computers

Yale University researchers have demonstrated one of the key steps in building the architecture for modular quantum computers: The "teleportation" of a quantum gate between...

Ultracold lithium atoms help verify a 1963 prediction about 1D electrons

Atomic physicists have verified a key prediction from a 55-year-old theory about one-dimensional electronics that is increasingly relevant thanks to Silicon Valley's inexorable quest...
A quantum gate between atoms and photons may help in scaling up quantum computers

A quantum gate between atoms and photons may help in scaling up quantum computers

The quantum computers of the future will be able to perform computations that cannot be done on today’s computers. These may likely include the ability...

‘Demon’ could help create quantum computer

Reduced entropy in a three-dimensional lattice of super-cooled, laser-trapped atoms could help speed progress toward creating quantum computers. A team of researchers at Penn...
