Some classical computers have error correction built into their memories based on bits; quantum computers, to be workable in the future, will need error correction mechanisms, too, based on the vastly...
MIT physicists predict exotic new phenomena and give “recipe” for realizing them（图）
奇异新现象 计算机 凝聚态物理
2023/6/6
In work that could lead to important new physics with potentially heady applications in computer science and more, MIT scientists have shown that two previously separate fields in condensed matter phy...
When two black holes collide into each other to form a new bigger black hole, they violently roil spacetime around them, sending ripples called gravitational waves outward in all directions. Previous ...
If she hits just the right pitch, a singer can shatter a wine glass. The reason is resonance. While the glass may vibrate slightly in response to most acoustic tones, a pitch that resonates with the m...
Physicists harness quantum “time reversal” to measure vibrating atoms（图）
量子 时间反转 振动原子 原子钟 量子传感器
2023/6/9
The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of ato...
Physicists discover a “family” of robust, superconducting graphene structures（图）
超导 石墨烯 结构“家族” 超导器件
2023/6/8
When it comes to graphene, it appears that superconductivity runs in the family.
Though they are discrete particles, water molecules flow collectively as liquids, producing streams, waves, whirlpools, and other classic fluid phenomena.
Not so with electricity. While an electric c...
Editor's note: This article has been updated to clarify that the new study in Physical Review Letters focuses on the detection of Unruh effect on a single accelerated particle, and to note that other ...
Physicists steer chemical reactions by magnetic fields and quantum interference（图）
磁场 量子干涉 化学反应 量子力学 超冷化学
2023/6/9
Physicists in the MIT-Harvard Center for Ultracold Atoms (CUA) have developed a new approach to control the outcome of chemical reactions. This is traditionally done using temperature and chemical cat...
Physicists observe an exotic “multiferroic” state in an atomically thin material（图）
原子薄材料 “多铁性”状态 磁存储设备
2023/6/7
MIT physicists have discovered an exotic “multiferroic” state in a material that is as thin as a single layer of atoms. Their observation is the first to confirm that multiferroic properties can exist...
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...
Physicists discover “secret sauce” behind exotic properties of a new quantum material（图）
量子材料 superconducting kagome metal 超导性
2023/6/7
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...
Physicists detect a hybrid particle held together by uniquely intense “glue”（图）
混合粒子 电子设备 基本粒子
2023/6/9
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...
Ultrathin materials made of a single layer of atoms have riveted scientists’ attention since the isolation of the first such material — graphene — about 17 years ago. Among other advances since then, ...
Ateam of physicists from the Harvard-MIT Center for Ultracold Atoms and other universities has developed a special type of quantum computer known as a programmable quantum simulator capable of operati...
