Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have developed a way for photographers and microscopists to create a 3D image through a single lens, without moving the camera.
Atomic clock precision could soon be used at home and work
A new development in fibre optic technology could soon bring atomic clock precision to any home or business with a fibre connection, according to researchers at The University of Western Australia and the University of Adelaide.
High-efficiency photon source brings day of reckoning closer for a famous quantum test
(Phys.org) —Physicists working at the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (JQI) are edging ever closer to getting really random.
New laser shows what substances are made of, could be new eyes for military (w/ video)
A new laser that can show what objects are made of could help military aircraft identify hidden dangers such as weapons arsenals far below.
Lab sets a new record for creating heralded photons
(Phys.org) —Entanglement, by general consensus of physicists, is the weirdest part of quantum science. To say that two particles, A and B, are entangled means that they are actually two parts of an inseparable ...
