Researchers from Leibniz University Hannover have made new discoveries in communication technology for quantum internet. The team at the Institute of Photonics showed something interesting. A laser pulse is a quick burst of light. An optical fiber is a thin strand of glass that transmits light over long distances. Entangled photons are tiny particles of light connected in a special way. These connections make quantum communication more secure.
This new method could combine regular data transmission with advanced quantum communication. It could lead to a hybrid network. This could have a big impact on telecommunications.
The quantum Internet promises enhanced security features that leverage the principles of quantum mechanics. According to Prof. Dr. Michael Kues, who leads the Institute of Photonics, He and his team have put this technology to practical use. They send entangled photons through fiber-optic networks. These special photons keep their unique properties during transmission. The breakthrough by Kues and his team is essential. It allows entangled photons to share a channel with regular data transmissions. This sharing happens without compromising the integrity of the entangled photons.
High speed electrical signals for quantum internet
A major challenge tackled by this research was the interference of entangled photons transmitted with regular light signals. The researchers showed an experimental setup. They altered the color of laser pulses using high-speed electrical signals. This made the laser pulses match the color of entangled photons. Philip Rübeling, a doctoral student, explained this. This feature enables the easy separation and subsequent recombination of photon types. This process happens inside an optical fiber. Optical fibers are thin strands of glass or plastic used to transmit light signals over long distances. This represents a significant advancement in multiplexing technology. Multiplexing is the process of combining and sending multiple signals over a single channel.
Developing hybrid systems for quantum internet
Before, the paths for entangled photons and traditional data streams could not share the same space. This new method now allows both to use the same optical fiber color channel. Jan Heine, one of Kues’ doctoral students, explained this. The earlier limitations happened because traditional methods blocked important channels in optical fibers. The findings hold great promise for developing hybrid systems capable of improved bandwidth utilization.
Secured Communication for the future
The implications for future networking infrastructures are significant. Hybrid networks use both classical and quantum methods. This combination could lead to new levels of data security and efficiency across platforms. Scientists are continually improving these technologies. We may soon have secure communications as a standard part of our daily lives.
Security protocols
Science Advances publishes the research results. These results show how integrations can create specialized environments. These environments need next-level security protocols. Such protocols are crucial for banking systems and governmental communications. These protocols are necessary because of current vulnerabilities with classical encryption methods. Classical encryption methods use mathematical algorithms to secure data but can be weak against advanced hacking techniques.
