Clouds come in all shapes and sizes. While we might imagine puppies or whales or breaking waves, climatologists look at them as massive bundles of water in various forms that contribute to the daily weather, and ultimately, climate. The numbers, shapes and sizes of the liquid drops and ice crystals contained in a cloud, for […]

Scientists have demonstrated that they can extend the lifetime of a molecular qubit by altering the surrounding crystal’s structure to be less symmetrical. The asymmetry protects the qubit from noise, enabling it to maintain information for five times longer than if it were housed in a symmetrical structure.

Although the word “qudit” might look like a typo, this lesser-known cousin of the qubit, or quantum bit, can carry more information and is more resistant to noise — both of which are key qualities needed to improve the performance of quantum networks, quantum key distribution systems and, eventually, the quantum internet.

There are many mysteries about the human brain. Being able to create comprehensive maps of the human brain to identify the location of every neuron and connection of the brain will help solve the mysteries.

A new deep-learning framework developed at the Department of Energy’s Oak Ridge National Laboratory is speeding up the process of inspecting additively manufactured metal parts using X-ray computed tomography, or CT, while increasing the accuracy of the results. The reduced costs for time, labor, maintenance and energy are expected to accelerate expansion of additive manufacturing, […]

In this experiment, NTT developed an ultra-wideband baseband amplifier IC module and digital signal processing technology that can compensate for distortion in the optical transceiver circuit with extremely high accuracy.

Genomic data from Indigenous communities plays an important role in understanding an array of diseases; however, this data has often been used without informed consent. A team of UC San Diego researchers—including San Diego Supercomputer Center affiliate Timothy Mackey—recently proposed a framework to utilize blockchain to ensure that Indigenous Data Sovereignty (IDS) is maintained during […]

An international research team, consisting of theoretical and applied physicists and computer scientists, has experimentally implemented a “bug-proof” type of quantum cryptography using quantum entanglement that could pave the way for secure communication between real-world devices. The post Does Quantum Entanglement Hold the Key to Unhackable Communications? appeared first on HPCwire.

With the Linpack exaflops milestone achieved by the Frontier supercomputer at Oak Ridge National Laboratory, the United States is turning its attention to the next crop of exascale machines, some 5-10x more performant than Frontier. At least one such system is being planned for the 2025-2030 timeline, and the DOE is soliciting input from the […]
