One of the most profound open questions in modern physics is: “Is gravity quantum?” The other fundamental forces—electromagnetic, weak, and strong—have all been successfully described, but no complete and consistent quantum theory of gravity yet […]

Scientists studying a promising quantum material have stumbled upon a surprise: within its crystal structure, the material naturally forms one of the world’s thinnest semiconductor junctions—a building block of most modern electronics. The junction is […]
The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely overlooked. Scientists at Forschungszentrum Jülich have now discovered that in certain materials it is not […]
Transistors are the fundamental building blocks behind today’s electronic revolution, powering everything from smartphones to powerful servers by controlling the flow of electrical currents. But imagine a parallel world, where we could apply the same […]
What if ultrafast pulses of light could operate computers at speeds a million times faster than today’s best processors? A team of scientists, including researchers from the University of Arizona, are working to make that […]
Quantum computers hold the potential to revolutionize the possibilities for solving difficult computational problems that would take classical computers many years to resolve. But for those computers to meet their potential, they need working quantum […]
In the world of quantum computing, the Hilbert space dimension—the measure of the number of quantum states that a quantum computer can access—is a prized possession. Having a larger Hilbert space allows for more complex […]
When a molecule absorbs light, it undergoes a whirlwind of quantum-mechanical transformations. Electrons jump between energy levels, atoms vibrate, and chemical bonds shift—all within millionths of a billionth of a second. Click to rate this […]
Two-dimensional (2D) materials have proved to be a promising platform for studying exotic quasiparticles, such as excitons. Excitons are bound states that emerge when an electron in a material absorbs energy and rises to a […]
Konstantin Vodopyanov, a professor at the College of Sciences and CREOL, the College of Optics and Photonics, recently co-authored a study published in the journal Optica. This research examines electro-optic sampling (EOS), a technique that […]
