Latest Quantum measurement Stories
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.
Entanglement, by general consensus of physicists, is the weirdest part of quantum science.
Like small children, scientists are always asking the question 'why?'. One question they've yet to answer is why nature picked quantum physics, in all its weird glory, as a sensible way to behave.
An international team of scientists has shed new light on a fundamental area of physics which could have important implications for future electronic devices and the transfer of information at the quantum level.
A team led by the Austrian physicist Anton Zeilinger has now carried out an experiment with photons, in which they have closed an important loophole.
"Spooky action at a distance" is how Albert Einstein rather famously described the theory of quantum entanglement. Until now, however, experiments attempting to examine this peculiar quantum mechanical phenomenon have been limited to relatively small distances on Earth.
One of the most basic laws of quantum mechanics is that a system can be in more than one state – it can exist in multiple realities – at once.
A University of Southampton academic has received a major research grant to help him explore the limitations of quantum theory.
Researchers at the University of Rochester and the University of Ottawa have applied a recently developed technique to directly measure for the first time the polarization states of light.
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.
