Scientists at the University of California, Riverside are making breakthroughs in understanding how quantum wave functions move across ultra-thin materials—research that could eventually improve solar energy technologies and help lay the groundwork for new forms of quantum computing. Go to Source In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in its suspended weights. This is done with the help of the escapement mechanism, which converts the gravitational energy of the weights into impulses that drive the pendulum, which then moves the clock’s gears, which […] Honeycombs are famous for their elegant design, but now they may have found a new application: quantum computing. To collect knowledge from subatomic particles, quantum computers require carefully designed materials capable of performing necessary, complex functions. However, the metals used, such as ruthenium and iridium, are often rare and expensive, limiting the potential to build […] Researchers in Spain have discovered that in collectives of moving fire ants, rippling “waves” of density and activity are likely triggered by local regions where ants collectively travel in the same direction as their neighbors. Go to Source Quantum mechanics is a physics framework that describes how matter and energy behave at an extremely small scale, specifically at the scale of atoms and subatomic particles. An effect predicted by the laws of quantum mechanics is superposition, which entails that particles can exist in multiple states or positions simultaneously, which remain indefinite until they […] Researchers at TU/e have demonstrated that energy transfer without loss via light or heat can occur over much greater distances than previously thought possible thanks to vibrations in microscopic gold rods. They succeeded in making energy jump from one particle to another over a distance of several millimeters without “spilling” energy along the way. Go […] Quantum computers have the potential to transform science, accelerating breakthroughs in drug development, cosmology, materials science, nuclear physics, and more. Go to Source Creating perfect randomness is surprisingly difficult. Even modern random number generators never generate completely ideal random numbers: small systematic errors can result in some numbers appearing slightly more frequently than others. For many applications, this does not matter. In cryptography, however, even the tiniest deviations can be problematic. Go to Source Ultra-fast data transfer and superconductivity: Quantum materials offer significant technological prospects—if we can understand them at the atomic scale. A team from the University of Geneva (UNIGE), in collaboration with the University of Salerno, the Institute of Materials Science of Barcelona, and the National Research Council of Italy, has succeeded in observing the “quantum metric” […] A study by researchers at The University of Manchester, carried out alongside the Universities of Melbourne and Copenhagen, could hold the key to understanding the causes of long-term health problems, such as infertility and ovarian cancer. Go to Source A growing number of quantum engineers worldwide have been trying to realize large-scale quantum networks, which consist of several connected quantum computers or devices that share information with each other. The successful realization of these networks could potentially pave the way for the realization of new high-speed and secure communication systems, or even of a […] Researchers have created a new theoretical framework that shows how memory-preserving “memtransistors” could overcome the intrinsic limits in efficiency faced by conventional semiconductor transistors, imposed by the laws of thermodynamics. Go to Source Whether the dust borne on the violent winds of a tornado or the sugar grains in a swirled cup of coffee, the behavior of particles carried along in turbulence is subject to some similarities—all of them difficult to predict at scale. As described in a recent publication in the Proceedings of the National Academy of […] A research team led by Professor Steven Wang, Associate Vice President (Resources Planning) and Associate Professor in the Department of Mechanical Engineering and School of Energy and Environment, has designed a revolutionary capillary structure that can trigger the Leidenfrost effect, offering a practical solution for the temperature-regulated Leidenfrost effect without requiring complex surface engineering. Go […] Spectroscopy has many applications, ranging from fundamental tests of quantum electrodynamics and investigations of molecular structure to environmental sensing, biomedical diagnostics and industrial monitoring. A highly promising spectroscopic instrument that has the potential to transform the field has emerged over the years: the dual-comb spectrometer, which relies on the interference of two mode-locked ultrafast lasers […] |
