'Compressive sensing' provides new approach to measuring a quantum system
(Phys.org) —In quantum physics, momentum and position are an example of conjugate variables. This means they are connected by Heisenberg's Uncertainty Principle, which says that both quantities cannot be ...
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 ...
Physicists propose explanation for metals behaving badly
Researchers use squeezed light to enhance photonic force microscopy
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.
Device for capturing signatures uses tiny LEDs created with piezo-phototronic effect
Researchers at the Georgia Institute of Technology want to put your signature up in lights – tiny lights, that is. Using thousands of nanometer-scale wires, the researchers have developed a sensor device ...
New mathematical model links space-time theories
Researchers at the University of Southampton have taken a significant step in a project to unravel the secrets of the structure of our Universe.

Testing Einstein's E=mc2 in outer space
(Phys.org)—University of Arizona physicist Andrei Lebed has stirred the physics community with an intriguing idea yet to be tested experimentally: The world's most iconic equation, Albert Einstein's E=mc2, may be cor ...
Revealing quantum flow
(Phys.org)—UK-based physicist Ole Steuernagel from the University of Hertfordshire, alongside Dimitris Kakofengitis and Georg Ritter, have found that a new powerful tool they call 'Wigner flow' is the quantum ...
Physicists extend entanglement in Einstein experiment
More certainty on uncertainty's quantum mechanical role
Scientists who study the ultra-small world of atoms know it is impossible to make certain simultaneous measurements, for example finding out both the location and momentum of an electron, with an arbitrarily ...
