In a breakthrough for antimatter research, the BASE collaboration at CERN has kept an antiproton—the antimatter counterpart ...

A century ago, the German physicists Otto Stern and Walther Gerlach carried out an experiment that gave an important credibility boost to the new-fangled notion of quantum mechanics. But as Hamish ...

Scientists have succeeded in unraveling the mystery of the ‘electron tunneling’ process for the first time. The feat, a core ...

The relationship between quantum mechanics and classical physics has baffled scientists for decades. In the quantum world, particles can exist in multiple states at once—a phenomenon known as ...

Quantum-physical model system Date: April 6, 2017 Source: University of Heidelberg Summary: Computer-assisted methods aid physicists in reproducing experiment with ultracold atoms.

Quantum mechanics dictates sensitivity limits in the measurements of displacement, velocity and acceleration. A recent experiment at the Niels Bohr Institute probes these limits, analyzing how ...

The experiment used partially entangled atoms that were a byproduct of an attempt to build quantum computers. Special relativity is a cornerstone of modern physics, and was formulated by Einstein ...

The double-slit experiment is the best demonstration of quantum weirdness, in which electrons simultaneously act like particles and waves and seemingly violate basic laws of physics. Now we’re ...

Putting quantum noise to work. The team did the experiment using several different types of operation for A and B and in all cases they found that the measured polarization of the output photons was ...

Instead quantum mechanics allows a particle’s residence to extend to the right-hand region of the cylinder, even if a residence in the left-hand region seems logically compelling.

In the latest experiment, run on just 9 qubits (the quantum equivalent of binary bits in classical computing) in Google’s Sycamore quantum processor, the team used machine learning to set up a ...
