Physicists discover atomic clock can simulate quantum magnetism
Researchers at JILA have for the first time used an atomic clock as a quantum simulator, mimicking the behavior of a different, more complex quantum system.
Effects of 'strong coupling' observed for the first time between light and a micromechanical object
(PhysOrg.com) -- Physicists at the Institute for Quantum Optics and Quantum Information (IQOQI) in Vienna and Innsbruck, Austria, have created an interaction between light and a micromechanical resonator that ...
Physicsts reveal how to cope with 'frustration'
For most people, frustration is a condition to be avoided. But for scientists studying certain "frustrated" ensembles of interacting components - that is, those which cannot settle into a state that minimizes ...
Artificial magnetic fields for light could illuminate correlated quantum systems
Quantum entanglement only dependent upon area
Two researchers at UCL Computer Science and the University of Gdansk present a new method for determining the amount of entanglement – a quantum phenomenon connecting two remote partners, and crucial for quantum technology ...
Rare earth ions in a crystal become candidate for a quantum memory
(Phys.org) —A promising material is lining itself up as a candidate for a quantum memory. A team at the Max Planck Institute for the Science of Light in Erlangen is the first to succeed in performing high-resolution ...
Making big 'Schroedinger cats': Quantum research pushes boundary by testing micro theory for macro objects
Since Erwin Schroedinger's famous 1935 cat thought experiment, physicists around the globe have tried to create large scale systems to test how the rules of quantum mechanics apply to everyday objects.
