Kilogramme faces quantum diet after weight problem
The guardians of the world's most important standards of weights and measures have turned to the weird universe of quantum physics to try to resolve a dilemma.
One clock with two times: When quantum mechanics meets general relativity
The unification of quantum mechanics and Einstein's general relativity is one of the most exciting and still open questions in modern physics. General relativity, the joint theory of gravity, space and time ...

Exotic quantum states: A new research approach
(PhysOrg.com) -- Theoretical physicists of the University of Innsbruck have formulated a new concept to engineer exotic, so-called topological states of matter in quantum mechanical many-body systems. They ...
Current flowing along the edges of a promising quantum device is insensitive to its magnetic impurities
Conductors of electrical current, including copper, heat up and limit the ability to increase circuit densities. Unusual materials that exhibit the so-called quantum spin Hall effect, in which ...
Redefining the kilogram and the ampere
New research using graphene presents the most precise measurements of the quantum Hall effect ever made, one of the key steps in the process to redefine two SI units.
Is graphene the best quantum resistance standard?
New research from NPL's Quantum Detection Group presents the most precise measurements of the quantum Hall effect ever made, using the two-dimensional material graphene.
Better 'photon loops' may be key to computer and physics advances
Surprisingly, transmitting information-rich photons thousands of miles through fiber-optic cable is far easier than reliably sending them just a few nanometers through a computer circuit. However, it may soon ...
Researchers create light from 'almost nothing'
Quantum physics first: Researchers observe single photons in two-slit interferometer experiment
Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And ...
Charge it: Neutral atoms made to act like electrically charged particles
(PhysOrg.com) -- Completing the story they started by creating synthetic magnetic fields, scientists from the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology a ...
Research sheds new light on black holes
(PhysOrg.com) -- The quantum phenomenon which is thought to cause black holes to leak energy and ultimately explode is more common than first thought according to Victoria University researchers.
Quantum engineers remove roadblock in developing next-generation technologies
(PhysOrg.com) -- An international team has removed a major obstacle to engineer quantum systems that will play a key role in the computers, communication networks, and even biomedical devices of the future.
NIST's new scanning probe microscope is supercool
The discoveries of superconductivity, the quantum Hall effect and the fractional quantum Hall effect were all the result of measurements made at increasingly lower temperatures. Now, pushing the regime of ...
