Rice Researchers Control Ultracold Rydberg Atoms to Imitate Quantum Interactions

The spatial sense of man does not extend outside the well-known three dimensions, but that does not prevent researchers from exploring with whatever lies outside.

Rice Scientists Discover a Way to Control Phonons Using Magnetic Field

Phonons are collective atomic vibrations, or quasiparticles, that act as the main heat carriers in a crystal lattice. Under certain circumstances, their properties can be modified by electric fields or light. But until now, nobody noticed they can respond to magnetic fields as well.

Quantum Light Approach Helps Achieve Substantial Improvement in Microscope Sensitivity

Lasers are often used to look at objects in microscopes. But even the best laser has "quantum noise" that makes a picture blurry and hides the details. This in turn results in measurements that are less precise than scientists need.

PhotonQ Project Receives EUR 16 Million to Develop a Photonic Quantum Processor

Quantum computers will one day be able to solve problems at high speed that cannot be handled by classical computer systems. However, in order for these computers to become practical, they must process a significantly higher number of qubits and have lower error rates. A research project led by Professor Stefanie Barz from the University of Stuttgart is now developing a photonic quantum processor for this purpose.

Physicists Manipulate Magnetism with Light

With the help of a “playground” they created for observing exotic physics, MIT scientists and colleagues have not only found a new way to manipulate magnetism in a material with light but have also realized a rare form of matter. The former could lead to applications including computer memory storage devices that can read or write information in a much faster way, while the latter introduces new physics.
