Both high-valued diamond and low-prized graphite consist of exactly the same carbon atoms. The subtle but nevertheless important difference between the two materials is the geometrical configuration of their building blocks, with large consequences for their properties.
What is light made of: waves or particles? This basic question has fascinated physicists since the early days of science. Quantum mechanics predicts that photons, particles of light, are both particles and waves simultaneously. Reporting in Science, physicists from the University of Bristol give a new demonstration of this wave-particle duality of photons, dubbed the 'one real mystery of quantum mechanics' by Nobel Prize laureate Richard Feynman.
Research and Markets has announced the addition of Woodhead Publishing Ltd's new book "Quantum optics with semiconductor nanostructures" to their offering.
Scientists who study the ultra-small world of atoms know it is impossible to make certain simultaneous measurements, for example finding out both the location and momentum of an electron, with an arbitrarily high level of precision. Because measurements disturb the system, increased certainty in the first measurement leads to increased uncertainty in the second.
Many quantum technologies—such as cryptography, quantum computing and quantum networks—hinge on the use of single photons. While she was at the Kastler Brossel Laboratory (affiliated with the Pierre and Marie...
Move over money, a new currency is helping make the world go round. As increasing volumes of data become accessible, transferable and, therefore, actionable, information is the treasure companies want to amass.
Through a new Multidisciplinary University Research Initiative (MURI) awarded by the Air Force Office of Scientific Research, researchers from Brown University will lead an effort to study new optical materials and their interactions with light quantum scale. The initiative, titled Quantum Metaphotonics and Quantum Metamaterials, will receive $4.5 million over three years, with a possible two-year extension.
CQT Principal Investigator Alexander Ling and his collaborators have written a feature for the more than 30,000 readers of Optics and Photonics News (OPN), a monthly magazine distributed to members of the Optical Society of America.
A Japanese-Australian collaborative research team has broken down the standard limits for ultra-precise measurement by exploiting quantum light waves in a different way.
At the World Economic Forum Annual Meeting of the New Champions 2012 held in Tianjin, China, Professor Jeremy O’Brien, Director of the Centre for Quantum Photonics at the University of Bristol, discussed about the future of information and communications technology (ICT) and how quantum technologies revolution will impact the future economics and society.
