In this method, photons that send and receive information are sent to a central node. The central node passes photons through a beam splitter and measures them. These results can reveal the correlation between these bits, but do not disclose their values, and remain secret. In this device, the green laser pointer information will remain secure even if the central node attempts to deceive.
This research technology makes quantum communication technology more secure and does not affect high clock rates in communication, which may indicate a way to actually implement quantum cryptography. New laser technology makes industrialization of graphene possible. Researchers at the Spanish Technology Center have demonstrated new technologies for processing graphene materials using ultra-high-speed lasers.
It makes it possible to produce graphene on a large scale. Relevant research papers were published in the Journal of Applied Physics Letters. Graphene has unique electronic and optical characteristics, and its industrial production may bring a new era of fast, reliable, and low power Green Laser Pointer communication and information processing.
