A tiny magnetic whirlpool could point to a new kind of ultra-efficient memory
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,
From spin wave to superconducting circuit: A one-way street for quantum information
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
