Revving up fluorescence for superfast LEDs: Researchers set speed record for molecular fluorescence
Duke University researchers have made fluorescent molecules emit photons of light 1,000 times faster than normal—setting a speed record and making an important step toward realizing superfast light emitting ...
Putting the squeeze on quantum information
Canadian Institute for Advanced Research researchers have shown that information stored in quantum bits can be exponentially compressed without losing information. The achievement is an important proof of principle, and could ...
Fluid mechanics suggests alternative to quantum orthodoxy
The central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. For most of the past century, the prevailing explanation of this conundrum ...
'Solid' light could compute previously unsolvable problems
Researchers at Princeton University have begun crystallizing light as part of an effort to answer fundamental questions about the physics of matter.
Researchers confirm 60-year-old prediction of atomic behavior
Researchers at Washington State University have used a super-cold cloud of atoms that behaves like a single atom to see a phenomenon predicted 60 years ago and witnessed only once since.
New analysis eliminates a potential speed bump in quantum computing
A quantum particle can search for an item in an unsorted "database" by jumping from one item to another in superposition, and it does so faster than a classical computer ever could.
Tricking the uncertainty principle
(Phys.org) —Caltech researchers have found a way to make measurements that go beyond the limits imposed by quantum physics.
Proving uncertainty: First rigorous formulation supporting Heisenberg's famous 1927 principle
Nearly 90 years after Werner Heisenberg pioneered his uncertainty principle, a group of researchers from three countries has provided substantial new insight into this fundamental tenet of quantum physics ...
Einstein's 'spooky' theory may lead to ultra-secure internet
(Phys.org) —Einstein's scepticism about quantum mechanics may lead to an ultra-secure internet, suggests a new paper by researchers from Swinburne University of Technology and Peking University.
A brake for spinning molecules
Chemical reactions taking place in outer space can now be more easily studied on Earth. An international team of researchers from the University of Aarhus in Denmark and the Max Planck Institute for Nuclear ...
Researchers propose using distant quasars to test Bell's theorem
In a paper published this week in the journal Physical Review Letters, MIT researchers propose an experiment that may close the last major loophole of Bell's inequality—a 50-year-old theorem that, if vio ...
Research team challenges the limits of famous quantum principle
(Phys.org) —A team of physicists is challenging the very limits of Heisenberg's famous uncertainty principle by measuring quantum particles with unprecedented accuracy.
Quantum physics in 1-D: New experiment supports long-predicted 'Luttinger liquid' model
How would electrons behave if confined to a wire so slender they could pass through it only in single-file?
Quantum mechanics explains efficiency of photosynthesis
Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous ...
