A major software advance could aid the creation of bigger, more reliable quantum computers, a study suggests. Researchers have developed an algorithm that enables off-the-shelf computers to run quantum simulations previously only possible using the world’s most powerful supercomputers.

Every time a computer stores or erases information, it uses energy. The amount is tiny for a single operation, but those operations happen billions of times every second. For decades, scientists have wondered just how little energy a memory device could use before reaching the fundamental theoretical limit set by the laws of physics. Now, researchers have shown that it is possible to come close.

Quantum information systems could one day shape everyday life through faster computing, sharper sensing and more secure communication. A new result from the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the University of Illinois Urbana-Champaign (U. of I.) marks an important step toward enabling magnetic spins—a quantum property of matter that can be used to store and manipulate information—to play a role in the future of quantum information processing.

Like the folds in crumpled sheets or the footprints on recently trodden sand, certain materials mark their histories. Now, Yale researchers show that networks of flowing water and other fluids can store their own memories—similar to how a computer chip does—an innovation that could steer robots and provide insight into some simple organisms. The results are published in Physical Review X.

Astronomers have found two actively feeding supermassive black holes separated by just 175 parsecs (570 light-years) in a galaxy seen when the universe was only about 2 billion years old. The system, MG B2016+112, lies at a redshift of 3.273 and is the most compact dual AGN known at this redshift. The study was posted to the arXiv preprint server on Sept. 25.

The space industry is rapidly expanding. About 20,000 satellites already circle Earth, a number that could reach 100,000 by 2030. They bring growing environmental costs: space debris, collision risks, atmospheric pollution from launches and reentry and interference with astronomical observations.

Understanding and controlling phase transitions are fundamental to physics and central to many technological revolutions. There is currently strong interest in materials with coupled structural and electronic phase transitions, where controlling the transition plasticity naturally yields built-in memory—a key step in emulating neurons and synapses for “neuromorphic” or brain-like computing technologies.

A research team from the Kyushu Institute of Technology, Kwansei Gakuin University, Tokyo City University, Kanazawa University, the University of Tokyo and other institutions has successfully completed the test operations conducted since the satellite was released into orbit. Having confirmed that the satellite meets its specified performance requirements, the team has begun routine operations for scientific astronomical observations.

Quantum networks are systems that connect different users or devices using principles of quantum mechanics. In the future, these networks could help improve the security of communications.
