Using the connected moments mathematical technique decreases the time and computational power needed for quantum computing simulations of chemical systems. The Science Advancing quantum computing requires models that can solve many-body problems quickly and accurately. These problems involve anywhere from three to an infinite number of particles so small they are subject to quantum mechanics. This research proposes a new algorithm for performing quantum calculations on chemical systems that reduces the effect of random “noise” on the results. The approach uses a…
Flaws in diamonds — atomic defects where carbon is replaced by nitrogen or another element — may offer a close-to-perfect interface for quantum computing, a proposed communications exchange that promises to be faster and more secure than current methods. There’s one major problem, though: these flaws, known as diamond nitrogen-vacancy centers, are controlled via magnetic field, which is incompatible with existing quantum devices. Imagine trying to connect an Altair, an early personal computer developed in 1974, to the internet via…
The innovation could be a game-changer for communication technologies, such as phones and internet connections. A team from UCF has developed the world’s first optical oscilloscope, an instrument that is able to measure the electric field of light. The device converts light oscillations into electrical signals, much like hospital monitorsconvert a patient’s heartbeat into electrical oscillation. Until now, reading the electric field of light has been a challengebecause of the high speeds at which light waves oscillates. The most advanced techniques, which power our phone and internet communications, can currently clock electric fields at up to gigahertz frequencies — covering…
High-precision 3D supercomputer simulations reveal the 3D structure of theoretically predicted micron-scale megatesla magnetic fields, optimizing engineering design of laser conditions and micron-size target structures for future laser experiments. Recently, a research team at Osaka University has successfully demonstrated the generation of megatesla (MT)-order magnetic fields via three-dimensional particle simulations on laser-matter interaction. The strength of MT magnetic fields is 1-10 billion times stronger than geomagnetism (0.3-0.5 G), and these fields are expected to be observed only in the close…
Researchers led by the University of Tsukuba present computer simulations that capture the complex dynamics of elusive neutrinos left over from the Big Bang. Current simulations of cosmic structure formation do not accurately reproduce the properties of ghost-like particles called neutrinos that have been present in the Universe since its beginning. But now, a research team from Japan has devised an approach that solves this problem. In a study published this month in SC ’21: Proceedings of the International Conference…
The microspeakers for wireless in-ear headphones from Arioso Systems GmbH, a spin-off of the Fraunhofer Institute for Photonic Microsystems IPMS, are up to ten times smaller than conventional microspeakers and are made entirely from silicon. Currently at the prototype stage, the energy-efficient MEMS speakers may in future play a role in expanding the range of functions offered by miniaturized headphones – such as instant translations and health monitoring features. This is made possible by an innovative sound transducer principle that…
Research team with participation of the University of Stuttgart succeeds in integrating color centers into nanophotonic silicon carbide structures. A promising route towards larger quantum computers is to orchestrate multiple task-optimised smaller systems. To dynamically connect and entangle any two systems, photonic interference emerges as a powerful method, due to its compatibility with on-chip devices and long-distance propagation in quantum networks. One of the main obstacles towards the commercialization of quantum photonics remains the nanoscale fabrication and integration of scalable…
Method combines quantum mechanics with machine learning to accurately predict oxide reactions at high temperatures when no experimental data is available; could be used to design clean carbon-neutral processes for steel production and metal recycling. Extracting metals from oxides at high temperatures is essential not only for producing metals such as steel but also for recycling. Because current extraction processes are very carbon-intensive, emitting large quantities of greenhouse gases, researchers have been exploring new approaches to developing “greener” processes. This…
Micro-sized cameras have great potential to spot problems in the human body and enable sensing for super-small robots, but past approaches captured fuzzy, distorted images with limited fields of view. Now, researchers at Princeton University and the University of Washington have overcome these obstacles with an ultracompact camera the size of a coarse grain of salt. The new system can produce crisp, full-color images on par with a conventional compound camera lens 500,000 times larger in volume, the researchers reported…
Our televisions and computer screens display news, movies, and shows in high-definition, allowing viewers a clear and vibrant experience. Fiber optic connections send laser light densely packed with data through cables to bring these experiences to users. NASA and commercial aerospace companies are applying similar technologies to space communications, bringing optical speeds to the final frontier. Free-space optical communications leverages recent advancements in telecommunications to allow spacecraft to send high-resolution images and videos over laser links. “Free-space” refers to the…
Artificial intelligence, hardware innovations boost confocal microscope’s performance. Since artificial intelligence pioneer Marvin Minsky patented the principle of confocal microscopy in 1957, it has become the workhorse standard in life science laboratories worldwide, due to its superior contrast over traditional wide-field microscopy. Yet confocal microscopes aren’t perfect. They boost resolution by imaging just one, single, in-focus point at a time, so it can take quite a while to scan an entire, delicate biological sample, exposing it light dosages that can…
Researchers outline in Science how brain research makes new demands on supercomputing. In the latest issue of Science, Katrin Amunts and Thomas Lippert explain how advances in neuroscience demand high-performance computing technology and will ultimately need exascale computing power. “Understanding the brain in all its complexity requires insights from multiple scales – from genomics, cells and synapses to the whole-organ level. This means working with large amounts of data, and supercomputing is becoming an indispensable tool to tackle the brain,”…
On-chip frequency shifters in the gigahertz range could be used in next generation quantum computers and networks. The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, including the Internet. The next generation of photonic technologies, such as photonic quantum networks and computers, will require even more control over the properties of a photon. One of the hardest properties…

To address the growing threat of cyberattacks on industrial control systems, a KAUST team including Fouzi Harrou, Wu Wang and led by Ying Sun has developed an improved method for detecting malicious intrusions. Internet-based industrial control systems are widely used to monitor and operate factories and critical infrastructure. In the past, these systems relied on expensive dedicated networks; however, moving them online has made them cheaper and easier to access. But it has also made them more vulnerable to attack,…
