Can you prove whether a large quantum system truly behaves according to the weird and wonderful rules of quantum mechanics—or if it just looks like it does? In a new study, physicists from Leiden, Beijing […]

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre world in which an object can act like both waves and particles, and behave differently depending on whether […]
In physics, there are two great pillars of thought that don’t quite fit together. The Standard Model of particle physics describes all known fundamental particles and three forces: electromagnetism, the strong nuclear force, and the […]
Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings physicists use to represent particle interactions. The new method has already enabled the researchers to […]
Researchers have discovered a simple yet powerful way to protect atoms from losing information—a key challenge in developing reliable quantum technologies. Click to rate this post! [Total: 0 Average: 0]You have already voted for this […]
Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a superposition of multiple states, as popularized by the Schrödinger’s cat analogy, and ability to slip through barriers, a phenomenon […]
Many systems obey simple, linear rules: If you pull twice as hard on a spring, it stretches twice as far. However, when we introduce very large forces or complicated interactions, that linear rule breaks down […]
Over the past few years, researchers have developed various quantum technologies, alternatives to classical devices that operate by leveraging the principles of quantum mechanics. These technologies have the potential to outperform their classical counterparts in […]
With the ability to detect and amplify extremely weak electromagnetic signals without adding additional noise, masers have many potential uses, including the production of more sensitive magnetic resonance body scanners, such as those used in […]
Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called “bright” excitons emit light and are therefore accessible, dark excitons are optically inactive. As a result, they have a […]
