Space-Based Gravitational-Wave Detector Uncovers Secrets of the Universe

According to a recent study, future space-based gravitational wave detections will be capable of discovering new basic forces and may offer fresh light on previously unsolved parts of the Universe.

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.

Astronomers Spot Unusual Object Unlike Anything Ever Seen Before

While mapping the universe for radio waves, researchers discovered a rare entity that discharges a massive burst of energy three times per hour, and it is unlike anything astronomers have ever observed.

New Qubits Could Make a Promising Foundation for Quantum Computers

MIT physicists have discovered a new quantum bit, or "qubit," in the form of vibrating pairs of atoms known as fermions.

Creating Matter Directly from Collisions of Light

Nuclear scientists have used a powerful particle accelerator to create matter directly from collisions of light. Scientists predicted this process in the 1930s, but it has never been achieved in a single direct step. The researchers accelerated two beams of gold ions to close to the speed of light in opposite directions.

A Leap-Ahead Technology for Generating Terahertz Radiation

Researchers have taken a major step towards bringing terahertz frequencies out of their hard-to-reach region of the electromagnetic spectrum and into everyday applications. In a new paper, the researchers demonstrate a first-of-its-kind terahertz laser that is compact, operates at room temperature and can produce 120 individual frequencies spanning the 0.25 - 1.3 THz, far more range than previous terahertz sources.

Scientists Make First Detection of Exotic “X” Particles in Quark-gluon Plasma

In the first millionths of a second after the Big Bang, the universe was a roiling, trillion-degree plasma of quarks and gluons — elementary particles that briefly glommed together in countless combinations before cooling and settling into more stable configurations to make the neutrons and protons of ordinary matter.
