There is a big problem with quantum technology—it's tiny. The distinctive properties that exist at the subatomic scale usually disappear at macroscopic scales, making it difficult to harness their superior sensing and communication capabilities for real-world applications, like optical systems and...

When atoms collide, their exact structure—for example, the number of electrons they have or even the quantum spin of their nuclei—has a lot to say about how they bounce off each other. This is especially true for atoms cooled to near-zero Kelvin, where quantum mechanical effects give rise to...

Atomic nuclei exhibit multiple energy scales simultaneously—ranging from hundreds down to fractions of a megaelectronvolt. A new study demonstrates that these drastically different scales can be explained through calculations based on the strong nuclear force. The research also predicts that the...

Researchers at North Carolina State University have demonstrated a new technique that uses light to tune the optical properties of quantum dots—making the process faster, more energy-efficient and environmentally sustainable—without compromising material quality....

Physicists have found a simple and effective way to skip over an energy level in a three-state system, potentially leading to increased quantum computational power with fewer qubits....

When it comes to layered quantum materials, current understanding only scratches the surface; so demonstrates a new study from the Paul Scherrer Institute PSI. Using advanced X-ray spectroscopy at the Swiss Light Source SLS, researchers uncovered magnetic phenomena driven by unexpected interactions...

Many objects that we normally deal with in quantum physics are only visible with special microscopes—individual molecules or atoms, for example. However, the quantum objects that Elena Redchenko works with at the Institute for Atomic and Subatomic Physics at TU Wien can even be seen with the naked...

Researchers from the National University of Singapore (NUS) and University of New South Wales (UNSW) Sydney have proven that a spinning atomic nucleus really is fundamentally a quantum resource. The teams were led respectively by Professor Valerio Scarani, from NUS Department of Physics, and...

One of the tiniest building blocks of the universe has a weigh-in problem, and Ashutosh Kotwal is determined to get to the bottom of it....

Devices that leverage quantum mechanics effects, broadly referred to as quantum technologies, could help to tackle some real-world problems faster and more efficiently. In recent years, physicists and engineers have introduced various promising quantum technologies, including so-called quantum...
