Imagine a material where electrons glide through without any resistance, moving like a perfectly synchronized dance troupe. This phenomenon, known as superconductivity, allows electricity to flow with zero energy loss, holding immense promise for everything from ultra-efficient power lines to advanced quantum computers. A a team of researchers dives into this fascinating world, focusing on […]

“God does not play dice.” This famous remark by Albert Einstein critiqued the probabilistic nature of quantum mechanics. Paradoxically, his theory of relativity has become an essential tool for understanding the behaviour of electrons, the primary subjects of quantum mechanics. Electrons are so minuscule that their behaviour must be analysed through quantum mechanics, yet they […]

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 and Hangzhou found the answer to this question. You could call it a “quantum lie detector”: Bell’s test designed by […]

When Georg Ohm wired up pieces of copper in 1827, he struck a rule so robust that it still underpins every phone and supercomputer on Earth: double the current, double the voltage. Simple, linear, universal—or so we thought. Over the past decade physicists have discovered that this bedrock principle crumbles the moment a crystal loses […]

When scientists place a single molecule on a surface and move electrons in or out one at a time, quantum mechanics comes to life in vivid detail. A team of researchers used a specialized microscope to study a copper-phthalocyanine (CuPc) molecule resting on a thin layer of salt. They discovered that the salt, far from […]

Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have theoretically demonstrated that photons trapped inside an optical cavity carry detailed information about a material placed within it. By measuring the properties of the photons leaking out of the cavity, researchers can probe how an optical cavity modifies the properties […]

In the realm of modern physics, few materials have captured the imagination quite like graphene, a single layer of carbon atoms arranged in a honeycomb lattice. Its remarkable properties, such as exceptional electrical conductivity and strength, have made it a cornerstone of research into quantum materials. A recent study published in Nature takes this fascination […]

In a leap forward for quantum computing, a Microsoft team led by UC Santa Barbara physicists on Wednesday unveiled an eight-qubit topological quantum processor, the first of its kind. The chip, built as a proof-of-concept for the scientists’ design, opens the door to the development of the long-awaited topological quantum computer. “We’ve got a bunch […]

Researchers have confirmed a theory that proposes a connection between the complementarity principle and entropic uncertainty. “Our results have no clear or direct application right now. It’s basic research that lays the foundation for future technologies in quantum information and quantum computers. There’s enormous potential for completely new discoveries in many different research fields,” says […]

A team of researchers has successfully demonstrated nonlinear Compton scattering (NCS) between an ultra-relativistic electron beam and an ultrahigh intensity laser pulse using the 4-Petawatt laser at the Center for Relativistic Laser Science (CoReLS) within the Institute for Basic Science at Gwangju Institute of Science and Technology (GIST), Korea. The innovation is the use of […]
