Physicists have used a seven-qubit quantum computer to simulate the scrambling of information inside a black hole, heralding a future in which entangled quantum bits might be used to probe the mysterious interiors of these bizarre objects.
Scrambling is what...
Dating back more than 3,000 years, knitting is an ancient form of manufacturing, but Elisabetta Matsumoto of the Georgia Institute of Technology in Atlanta believes that understanding how stitch types govern shape and stretchiness will be invaluable for designing...
The universe is almost devoid of antimatter, and physicists haven't yet figured out why. Discovering any slight difference between the behaviour of antimatter and matter in Earth's gravitational field could shed light on this question. Positronium atoms, which consist...
Researchers at Tokyo Institute of Technology (Tokyo Tech) have developed an easy-to-use, tunable biosensor tailored for the terahertz range. Images of mouse organs obtained using the new device verify that the sensor is capable of distinguishing between different tissues....
Electronic devices such as transistors are getting smaller and will soon hit the limits of conventional performance based on electrical currents.
Devices based on magnonic currents—quasi-particles associated with waves of magnetization, or spin waves, in certain magnetic materials—would transform the industry, though...
The force is strong not only in Star Wars lore but also as a fundamental property in physics. For example, scientists can put two uncharged metal plates close together in a vacuum, and "voila!" —-they will attract each other...
A recently discovered Weyl semimetal delivers the largest intrinsic conversion of light to electricity of any material, an international team lead by a group of Boston College researchers reports today in the journal Nature Materials.
The discovery is based on a...
Shortfin mako sharks have been called the "cheetahs of the ocean," capable of swimming at estimated speeds of 70 or 80 miles per hour. To investigate just how the animals achieve this impressive feat, aeronautical engineer Amy Lang of...
You've probably seen this effect—perhaps you are a victim of it. You feel alienated from mainstream culture and want to make a statement that you are not part of it. You think about wearing different clothes, experimenting with a...
For the first time, researchers have demonstrated a way to map and measure large-scale photonic quantum correlation with single-photon sensitivity. The ability to measure thousands of instances of quantum correlation is critical for making photon-based quantum computing practical.
In Optica, The...
One of the key concepts in quantum physics is entanglement, in which two or more quantum systems become so inextricably linked that their collective state can't be determined by observing each element individually. Now Yale researchers have developed a...
