Researchers document a quantum spin wave for light

Researchers at Purdue University have created a quantum spin wave for light. This can be a carrier of information for future nanotechnologies but with a unique twist: they only flow in one direction.

Physicists discover new type of spin waves

Current technologies for information transfer and processing are challenged by fundamental physical limits. The more powerful they become, the more energy they need, and the more heat is released to the environment. Also, ...

Spin lasers facilitate rapid data transfer

Engineers at Ruhr-Universität Bochum have developed a novel concept for rapid data transfer via optical fibre cables. In current systems, a laser transmits light signals through the cables and information is coded in the ...
