In the first study of its kind at the Large Hadron Collider (LHC), the CMS collaboration has tested whether top quarks adhere to Einstein's special theory of relativity. The research is published in the journal Physics Letters B....
Researchers at the University of Basel have shown that quantum systems can have antagonistic interactions, too—one agent attracts the other, but the other way around, there is a repulsion. Such interactions could be realized using cold atoms that are coupled to each other....
Quantum entanglement—a phenomenon where particles are mysteriously linked no matter how far apart they are—presents a long-standing challenge in the physical world, particularly in understanding its behavior within complex quantum systems....
Quantum computers have the potential of outperforming classical computers on some optimization tasks. Yet scaling up quantum computers leveraging existing fabrication processes while also maintaining good performances and energy-efficiencies has so far proved challenging, which in turn limits their...
In a new Nature Communications study, scientists have demonstrated the quantum version of the strong Mpemba effect (sME) in a single trapped ion system....
Topological insulators (TIs) are among the hottest topics in condensed matter physics today. They're a bit strange: Their surfaces conduct electricity, yet their interiors do not, instead acting as insulators. Physicists consider TIs the materials of the future because they host fascinating new...
Molecules haven't been used in quantum computing, even though they have the potential to make the ultra-high-speed experimental technology even faster. Their rich internal structures were seen as too complicated, too delicate, too unpredictable to manage, so smaller particles have been used....
A research team discovered a quantum state in which electrons move in a completely new way under a twisted graphene structure. The unique electronic state is expected to contribute to the development of more efficient and faster electronic devices. It may also be applicable to technologies such as...
Phonons, the quantum mechanical vibrations of atoms in solids, are often sources of noise in solid-state quantum systems, including quantum technologies, which can lead to decoherence and thus adversely impact their performance....
A kind of umbilical cord between different quantum states can be found in some materials. Researchers at TU Wien have now shown that this "umbilical cord" is generic to many materials....
