Latest Quantum measurement Stories
Ever since Austrian scientist Erwin Schrodinger put his unfortunate cat in a box, his fellow physicists have been using something called quantum theory to explain and understand the nature of waves and particles.
Whether a quantum object behaves like a wave or like a particle depends (according to the Copenhagen interpretation) on the choice of measurement apparatus used for observing the system, and therefore on the type of measurement performed.
A research team led by the University of Vienna has developed a new method for entangling single photons that gyrate in opposite directions.
Physicists have proposed an experiment that could force us to make a choice between extremes to describe the behavior of the Universe.
Since 1927, when Werner Heisenberg formulated the uncertainty principle, it has stood as one of the cornerstones of quantum mechanics. It has also driven quantum physicists crazy for nearly a century.
An international team of researchers has achieved quantum teleportation over a record distance of 143 kilometers. The experiment marks a major step towards satellite-based quantum communication.
A fundamental characteristic of quantum physics is the fact that two or more particles can exhibit correlations stronger than classically allowed.
Theoretical physicist Filippo Miatto and colleagues from the University of Strathclyde, Glasgow, UK, have found a new method of reliably assessing the information contained in photon pairs used for applications in cryptography and quantum computing.
Many of the predictions we make in everyday life are vague, and we often get them wrong because we have incomplete information, such as when we predict the weather.
Quantum technologies promise to redefine the landscape of information processing and communication.
