Like the transistors in a classical computer, superconducting qubits are the building blocks of a quantum computer. While engineers have been able to shrink transistors to nanometer scales, however, s...
MIT physicists have discovered a new quantum bit, or “qubit,” in the form of vibrating pairs of atoms known as fermions. They found that when pairs of fermions are chilled and trapped in an optical la...
Time crystals. Microwaves. Diamonds. What do these three disparate things have in common?
In the first millionths of a second after the Big Bang, the universe was a roiling, trillion-degree plasma of quarks and gluons — elementary particles that briefly glommed together in countless combin...
MIT physicists and colleagues have discovered the “secret sauce” behind some of the exotic properties of a new quantum material that has transfixed physicists due to those properties, which include su...
The atomic nucleus is a tough nut to crack. The strong interaction between the protons and neutrons that make it up depends on many quantities, and these particles, collectively known as nucleons, are...
With a little twist and the turn of a voltage knob, Cornell researchers have shown that a single material system can toggle between two of the wildest states in condensed matter physics: the quantum a...
In the particle world, sometimes two is better than one. Take, for instance, electron pairs. When two electrons are bound together, they can glide through a material without friction, giving the mater...
法国高等教育、研究与创新部2022年1月4日发布新闻公报说,在法国量子技术国家投资规划框架下,政府当日宣布启动全国量子计算平台,旨在更好推动量子技术的应用和发展。根据公报,该平台拥有初始投资7000万欧元,目标投资总额1.7亿欧元。平台将以法国替代能源与原子能委员会运行的超大计算中心(TGCC)为载体,由法国计算机科学和自动化研究所提供支持。平台致力于将量子计算机和传统计算机系统进行联通,面向国际...
In a paper published today in the journal Nature, the BASE collaboration at CERN reports the most precise comparison yet between protons and antiprotons, the antimatter counterparts of protons.
To make fusion energy a viable resource for the world’s energy grid, researchers need to understand the turbulent motion of plasmas: a mix of ions and electrons swirling around in reactor vessels. The...
A crystal structure that combines a semiconductor and superconductor is a tantalizing prospect to create energy-efficient computers, or quantum computers, which leverage the unique quantum mechanical ...
近日,南华大学核科学技术学院硕士研究生李诗铭同学在其导师毛飞副教授的指导下在物理学国际权威期刊《Physical Review B》上发表题为《First-principles study of the electronic stopping power of indium for protons and He ions》的学术论文。《Physical Review B》是凝聚态物理学和材料物理学...
2021年11月29-30日,IEEE iWEM 2021(IEEE International Workshop on Electromagnetics:Applications and Student Innovation Competition)(第十一届国际电磁学研讨会)成功举办。本次会议由华南理工大学电子与信息学院主办,人工智能与数字经济广东省实验室协办,得到了广州市科学技术协会的指导,...
2021年11月29日,由中国原子能科学研究院主导编制的全球首个回旋加速器国际标准IEC63175:2021《10MeV~30MeV范围内固定能量强流质子回旋加速器》正式发布,填补了回旋加速器国际标准的空白,对带动我国回旋加速器创新研发和型谱化、规模化推广应用具有重要意义。这是原子能院继今年11月在核燃料领域、通用仪器领域分别发布两项国际标准后,又一项国际化标准重要成果,标志着我国核科学技术水平进...
