The laser trick that could put an ultraprecise optical clock on a chip Researchers have made a key breakthrough in how light is used to control time signals from the world’s most precise clocks. The technique marks a crucial step in bringing this technology into everyday life. Mengxi Tan...
Just like a mobile phone call can suffer interference leading it to break up, a quantum computer is susceptible to interference from all sorts of sources, like electromagnetic signals coming from WiFi or disturbances in the Earth’s magnetic field. When qubits in a quantum computer are exposed ...
Join in expert discussion on quantum physics. Quantum physics is the mathematical description of the motion and interaction of subatomic particles. Quantum...
” says Mohammadamin Tajik. “In a classical many-body system, coherence disappears; you can say the particles no longer know anything about their neighboring particles.” The effect of temperature and coherence length on mutual information was also confirmed in the experiment....
Theory Confirmed: A Long-Awaited Breakthrough Eight years ago, Roderich Moessner theorized that a quantum tornado could also form in momentum space. At the time, the Dresden-based ct.qmat co-founder described the phenomenon as a “smoke ring” because, like smoke rings, it consists of vortices...
Quantum error correction of a logical qutrit and ququart were experimentally realized beyond the break-even point with the Gottesman–Kitaev–Preskill bosonic code. Benjamin L. Brock Shraddha Singh Michel H. Devoret ResearchOpen Access14 May 2025 Nature Volume: 641, P: 612-618 Nonlinear stochas...
Google and others. It's named for quantum physics, which describes the forces of the subatomic realm. And as we told you last winter, the science is deep and we can't scratch the surface, but we hope to explain just enough so that you won't be blindsided by a breakthrough that could...
This breakthrough in quantum simulation technology is expected to propel advancements in quantum physics research and quantum computing, said Pan Jianwei, a renowned Chinese quantum physicist and an academician of the Chinese Academy of Sciences (CAS), at a press conference. ...
(双缝实验)根据量子力学,我们不能把穿越过狭缝的物体形容为一个实体对象。我们唯一能说的是,这些电子可能具有概率,这种概率波以某种方式穿越两条狭缝,并形成干涉,就如同水波那样,当其达到屏幕时,刚才那具有灵魂般概率的电子,又神秘地变回实体。Quantum mechanics says this ,we can't describe what's travelling as...
of Lorentz invariance, and place a lower limit of 1.2E(Planck) on the scale of a linear energy dependence (or an inverse wavelength dependence), subject to reasonable assumptions about the emission (equivalently we have an upper limit of l(Planck)/1.2 on the length scale of the effect). ...
