Physicists prove Heisenberg's intuition correct
An international team of scientists has provided proof of a key feature of quantum physics – Heisenberg's error-disturbance relation - more than 80 years after it was first suggested.
Forbidden quantum leaps possible with high-resolution spectroscopy
A new twist on an old tool lets scientists use light to study and control matter with 1,000 times better resolution and precision than previously possible.
New approach uses 'twisted light' to increase efficiency of quantum cryptography systems
Researchers at the University of Rochester and their collaborators have developed a way to transfer 2.05 bits per photon by using "twisted light." This remarkable achievement is possible because the researchers ...

Black hole that doesn't emit x-rays discovered near massive star
SLAC scientists create twisted light
(Phys.org) —Scientists at SLAC have found a new method to create coherent beams of twisted light – light that spirals around a central axis as it travels. It has the potential to generate twisted light ...
Scientists score one more victory over uncertainty in quantum physics measurements
(PhysOrg.com) -- Most people attempt to reduce the little uncertainties of life by carrying umbrellas on cloudy days, purchasing automobile insurance or hiring inspectors to evaluate homes they might consider ...
New theory points to 'zombie vortices' as key step in star formation
(Phys.org) —A new theory by fluid dynamics experts at the University of California, Berkeley, shows how "zombie vortices" help lead to the birth of a new star.
