Latest Photon Stories
The Information Age will get a major upgrade with the arrival of quantum processors many times faster and more powerful than today’s supercomputers.
A team of engineers from MIT has announced the development of a highly-efficient lidar rangefinder; a device that allows autonomous vehicles to ‘see’ what is in front of them and surveyors to measure distances.
An international team of scientists has shown for the first time that atoms can work collectively rather than independently of each other to share light.
Physicists at the University of Basel have been successful in generating photons - the quantum particles of light – with only one color.
MIT physicists have proposed a new experiment to look for the elusive dark matter particle known as the 'A Prime' particle.
Imagine you order a delivery of several glass vases in different colors. Each vase is sent as a separate parcel. What would you think of the courier if the parcels arrive apparently undamaged, yet when you open them, it turns out that all the red vases are intact and all the green ones are smashed to pieces?
In celebration of the publication’s 25th anniversary, Physics World has selected the five most important physics-related discoveries of the past quarter-century, as well as five recent breakthroughs with the potential to change the world.
A quantum computer can solve tasks where a classical computer fails.
University of Calgary scientists have overcome an 'Achilles' heel' of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets.
Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...
Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...
