Scientists have devised a breakthrough laser that uses a single artificial atom to generate and emit particles of light. The laser may play a crucial role in the development of quantum computers, which are predicted to eventually outperform today's most powerful supercomputers.
Imagine being able to instantaneously run an optical cable or fiber to any point on Earth, or even into space. Researchers now report using an 'air waveguide' to enhance light signals collected from distant sources. These air waveguides could have many applications, including long-range laser communications, detecting pollution in the atmosphere, making high-resolution topographic maps and laser weapons.
Vacuum fluctuations may be among the most counter-intuitive phenomena of quantum physics. Theorists have now proposed a way to amplify their force. The researchers believe that their proposed enhancement of the power of vacuum fluctuations can have profound implications for understanding Casimir and Van der Waals forces and it may even be used for applications in quantum information processing and other emerging quantum technologies.
Do you have a fascination with Einstein's theory of relativity? What I mean is, do you find yourself fascinated by the weird predictions of this theory and would like to get to the bottom of it once and for all? While relativity ...
