Tensor networks take a central role in quantum physics as they can provide an efficient approximation to specific classes of quantum states. The associated graphical language can also easily describe and pictorially reason ...
A pair of researchers, one at the Massachusetts Institute of Technology (MIT) and another at California Institute of Technology (Caltech) and the University of Tokyo, have recently investigated a set of old conjectures about ...
Researchers have developed a new approach to multicolor holography that could be used to make 3-D color displays for augmented reality glasses, smartphones or heads-up displays without any bulky optical components.
While most interaction with digital content is still constrained to keyboards and 2-D touch panels, augmented and virtually reality (AR/VR) technologies promise ever more freedom from these limitations.
The modern-day theoretical physicist faces a taxing uphill climb. "As we learn more, reality becomes ever more subtle; the absolute becomes relative, the fixed becomes dynamical, the definite is laden with uncertainty," writes ...
Heads-up displays are transparent devices used in airplanes and cars to provide information such as critical flight data or driving directions on the windshield. An innovative holography-based approach could soon make these ...
People usually associate holograms with futuristic 3-D display technologies, but in reality, holographic technologies are now being used to study materials at the atomic level. X-rays, a high-energy form of light, are often ...
Optical engineers from ITMO University in Saint Petersburg developed an express method for estimating the distribution of particles in optically transparent media based on correlation analysis of holograms. As a big part ...
Nanophotonic circuits, tiny chips which filter and steer light, suffer from small random variations which degrade the transmission of light. Researchers have now found a way to compensate those variations, which may lead ...
Until quite recently, creating a hologram of a single photon was believed to be impossible due to fundamental laws of physics. However, scientists at the Faculty of Physics, University of Warsaw, have successfully applied ...
