(PhysOrg.com) -- Physics researchers working at the National Research Council in Canada have succeeded in developing a way to directly measure the wavefunction of a photon. The technique, as described in their paper published in Nature, combines both strong and weak measurements, and offers researchers a new tool for use in understanding the intricacies of quantum mechanics

By Eric Hand of Nature magazine Can the time-warping ways of Einstein's theory of general relativity be measured by the quantum 'ticking' of an atom? In 2010, researchers at the University of California, Berkeley, claimed in Nature that they had used an inexpensive table-top apparatus to show how gravity had altered a fundamental oscillation of two atoms.

(PhysOrg.com) -- Last week, Burnaby, British Columbia-based company D-Wave Systems, Inc., announced that it sold its first commercial quantum computer. Global security company Lockheed Martin, based in Bethesda, Maryland, bought the quantum computer for a rumored $10 million, which includes maintenance and other services for several years.

(PhysOrg.com) -- Scientists at the Max Planck Institute of Quantum Optics prepare quantum mechanical entanglement of two remote quantum systems.

Quantum Health's employee-run "cultural councils" build and maintain equilibrium within its offices. Servicing the healthcare industry can be especially tiresome, so Quantum Health strives to keep its employees happy and functional

(PhysOrg.com) -- A data memory can hardly be any smaller: researchers working with Gerhard Rempe at the Max Planck Institute of Quantum Optics in Garching have stored quantum information in a single atom. The researchers wrote the quantum state of single photons, i.e. particles of light, into a rubidium atom and read it out again after a certain storage time

(PhysOrg.com) -- An international team of researchers succeeded at the Max Planck Institute of Quantum Optics to control and monitor strongly accelerated electrons from nano-spheres with extremely short and intense laser pulses. (Nature Physics, 24

(PhysOrg.com) -- Quantum computing holds great promise, but will require informed specialists who can explore its full potential. Through a book, an interdisciplinary class and now a brand new online tool, University of Cincinnati Professor Marc Cahay is preparing students for this emerging field.

Quantum information science is a bit like classroom management--the larger the group, the harder it is to keep everything together. [More]

For the first time – as presented in Nature Communications - the quantum behaviour of molecules consisting of more than 400 atoms was demonstrated by quantum physicists based at the University of Vienna in collaboration with chemists from Basel and Delaware.

(PhysOrg.com) -- Quantum physicists from the University of Innsbruck (Austria) have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced. With this experiment the scientists have not only come closer to the realization of a quantum computer but they also show surprising results for the quantum mechanical phenomenon of entanglement.

(PhysOrg.com) -- When most of us think of entanglement, our minds jump immediately to quantum communication. "Entanglement has become very well known and useful in quantum communication," Robert Prevedel tells PhysOrg.com. Prevedel, a scientist at the Institute for Quantum Computing at the University of Waterloo in Ontario, Canada, believes that entanglement can be used in classical communication as well.

(PhysOrg.com) -- In the classical world, information can be copied and deleted at will. In the quantum world, however, the conservation of quantum information means that information cannot be created nor destroyed. This concept stems from two fundamental theorems of quantum mechanics: the no-cloning theorem and the no-deleting theorem.

(PhysOrg.com) -- Quantum computers are computers that exploit the weird properties of matter at extremely small scales. Many experts believe that a full-blown quantum computer could perform calculations that would be hopelessly time consuming on classical computers, but so far, quantum computers have proven hard to build.
