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 ...
Almost 200 years ago, Bavarian physicist Joseph von Fraunhofer discovered dark lines in the sun's spectrum. It was later discovered that these spectral lines can be used to infer the chemical composition and temperature of ...
Recently, academic debate has been swirling around the existence of unusual quantum mechanical effects in the most ubiquitous of phenomena, including photosynthesis, the process by which organisms convert light into chemical ...
While many of us enjoyed constructing little houses out of toy bricks when we were kids, this task is much more difficult if bricks are elementary particles. It is even harder if these are particles of light - photons, which ...
Researchers at the California Institute of Technology (Caltech) have proposed a new paradigm that should allow scientists to observe quantum behavior in small mechanical systems.
Using a convenient and flexible method for creating twin light beams, researchers from the National Institute of Standards and Technology (NIST) and the University of Maryland (UM) have produced “quantum images,” pairs ...
Using a convenient and flexible method for creating twin light beams, researchers at the Joint Quantum Institute of the Commerce Department's National Institute of Standards and Technology and the University of Maryland have ...
One of the problems plaguing classical communication is associated with what is known as the Byzantine agreement. In this problem, messages between three different parties are subject to faulty information. Quantum communication, ...
An international team including scientists from the London Centre for Nanotechnology (LCN) today publishes findings in the journal Proceedings of the National Academy of Sciences demonstrating the dramatic effects of quantum ...
Declaring that it is always useful to start a lecture with a literary quote, Professor Sir Peter Knight began his on quantum entanglement with the statement: "Let's just say we want to avoid any Imperial entanglements."
