If you’ve ever been in a supercomputer datacenter, you’ll know that they don’t tend to be quiet places – but now, supercomputing is helping make some machinery hum quieter. ebm-papst, a German fan and electric motor manufacturer, is applying the Hawk supercomputer at the High-Performance Computing Center Stuttgart (HLRS) to understand how and why its […]

Predicting the properties of a molecule or material requires calculating the collective behavior of its electrons. Such predictions could one day help researchers develop new pharmaceuticals or design materials with sought-after properties such as superconductivity. The problem is that electrons can become ‘quantum mechanically’ entangled with one another, meaning they can no longer be treated […]

As semiconductor devices become ever smaller, researchers are exploring two-dimensional (2D) materials for potential applications in transistors and optoelectronics. Controlling the flow of electricity and heat through these materials is key to their functionality, but first we need to understand the details of those behaviors at atomic scales. The post Electronic Bridge Allows Rapid Energy […]

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory report they can precisely rotate a single molecule that small on demand. The key ingredient is a single atom of europium, a rare earth element. It rests at the center of a complex of different atoms and gives the molecule many potential applications. The […]

An international team of scientists have demonstrated a leap in preserving the quantum coherence of quantum dot spin qubits as part of the global push for practical quantum networks and quantum computers. These technologies will be transformative to a broad range of industries and research efforts: from the security of information transfer, through the search […]

The root of the team’s approach is multilevel modeling (MLM, not to be confused with multilevel marketing). Through MLM, groups of similar cases are bundled and differential equations are used to identify a limited set of controlling factors for each case, allowing for easier – and more consistent – identification of the model’s reasoning compared […]

A study by chemists at the University of Chicago has uncovered a new key step in the process that HIV uses to replicate itself. The post Tiny Ion Is Crucial for HIV Replication: Supercomputer Simulation Explains How Viruses Form Capsids appeared first on HPCwire.

Quantum sensing represents one of the most promising applications of quantum technologies, with the aim of using quantum resources to improve measurement sensitivity. In particular, sensing of optical phases is one of the most investigated problems, considered key to developing mass-produced technological devices. The post Deep Learning for Quantum Sensing: AI Assists Quantum Metrology for […]

Excitons are drawing attention as possible quantum bits (qubits) in tomorrow’s quantum computers and are central to optoelectronics and energy-harvesting processes. However, these charge-neutral quasiparticles, which exist in semiconductors and other materials, are notoriously difficult to confine and manipulate. Now, for the first time, researchers have created and directly observed highly localized excitons confined in […]

On December 5th, the research team at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) achieved a historic win in energy science: for the first time ever, more energy was produced by an artificial fusion reaction than was consumed – 3.15 megajoules (MJ) produced versus 2.05 megajoules in laser energy to cause […]
