Quantum physics just got less complicated
Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers has proved that two peculiar features of the quantum world previously considered distinct ...
'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 ...
A bound on the natural width of the Higgs boson
CMS has improved the constraints on the Higgs width, a fundamental property of this unique new particle, by more than two orders of magnitude.
Physicists propose explanation for metals behaving badly
Researchers use squeezed light to enhance photonic force microscopy
Researchers use quantum entanglement to improve differential interference contrast 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.
Teleportation just got easier—but not for you, unfortunately
Thanks to two studies published in Nature last Thursday, the chance of successful teleportation has considerably increased. Which is a good thing, right? ...
'Listening' to black holes form with gravity waves
New technology that breaks the quantum measurement barrier has been developed to detect the gravity waves first predicted by Einstein in 1916.
Uncertainty revisited: Novel tradeoffs in quantum measurement
Hydrogen atoms under the magnifying glass
To describe the microscopic properties of matter and its interaction with the external world, quantum mechanics uses wave functions, whose structure and time dependence is governed by the Schrödinger equation. ...
Physicists successfully transmit secure quantum code through atmosphere from aircraft to ground station
(Phys.org) —Can worldwide communication ever be fully secure? Quantum physicists believe they can provide secret keys using quantum cryptography via satellite. Unlike communication based on classical bits, ...
