Playing quantum tricks with measurements
A team of physicists at the University of Innsbruck, Austria, performed an experiment that seems to contradict the foundations of quantum theory—at first glance. The team led by Rainer Blatt reversed a ...
Verifying the future of quantum computing
Physicists are one step closer to proving the reliability of a quantum computer – a machine which promises to revolutionise the way we trade over the internet and provide new tools to perform powerful simulations.
Quantum microscope for living biology
(Phys.org)—A team of Australian scientists has developed a powerful microscope using the laws of quantum mechanics to probe the inner workings of living cells.
Einstein's 'spooky action' common in large quantum systems, mathematicians find
Entanglement is a property in quantum mechanics that seemed so unbelievable and so lacking in detail that, 66 years ago this spring, Einstein called it "spooky action at a distance." But a mathematician at Case Western Reserve ...
For the first time, researchers observe collective spin dynamics of ultra-cold fermions with large spins
Understanding collective behavior of ultra-cold quantum gases is of great interest since it is intimately related to many encountered systems in nature such as human behavior, swarms of birds, traffic jam, sand dunes, neutron ...
Link between quantum physics and game theory found
(Phys.org) —A deep link between two seemingly unconnected areas of modern science has been discovered by researchers from the Universities of Bristol and Geneva.
Physics duo suggest using early universe inflation as graviton detector
Researchers make headway in quantum information transfer via nanomechanical coupling
Fiber optics has made communication faster than ever, but the next step involves a quantum leap –– literally. In order to improve the security of the transfer of information, scientists are working on ...
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.
Researchers use squeezed light to enhance photonic force microscopy
Our ambiguous world of words
(Phys.org) —Ambiguity in language poses the greatest challenge when it comes to training a computer to understand the written word. Now, new research aims to help computers find meaning.
Researchers discover a way to avoid decoherence in a quantum system
When fluid dynamics mimic quantum mechanics
In the early days of quantum physics, in an attempt to explain the wavelike behavior of quantum particles, the French physicist Louis de Broglie proposed what he called a "pilot wave" theory. According to ...
Physicists publish solution to the quantum measurement problem
(Phys.org) —Quantum mechanics is a highly successful theory, but its interpretation has still not been settled. In their recent opus magnum, Theo Nieuwenhuizen (Institute of Physics, UvA) and colleagues claim to have found ...
