即使能量流失,也能读取光中的隐藏拓扑

当我向学生解释拓扑学时,我通常从绳结开始。你可以拉伸、扭曲或晃动它,但除非剪断绳子,否则结一直都在。物理学家发现,某些材料和设备在波通过它们时也带有类似的“结”。这些是拓扑特性,由在微小缺陷下保持不变的整数标记。这种鲁棒性正是拓扑学成为现代物理学核心概念之一的原因。它有望催生出能够容忍缺陷和噪声的电子、光子和量子器件。

Jamming the flow to enable memory in quantum materials

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.

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 used to store and manipulate information—to play a role in the future of quantum information processing.
