Hanover, Germany – A groundbreaking discovery by researchers at the Leibniz University Hanover (LUH) has paved the way for the integration of quantum internet and traditional internet, marking a significant milestone in the field of telecommunications.
The research team, based at the Institute of Photonics at LUH, has developed a novel technique for transmitting entangled photons through optical fibers, enabling the seamless fusion of quantum internet and traditional internet. This breakthrough has the potential to enhance security and efficiently utilize existing infrastructure.
Innovative System for Entangled Photon Transmission
The team, consisting of four researchers, has developed an innovative发射接收系统 for transmitting entangled photons through optical fibers. This system allows for the integration of quantum internet, which is expected to implement unbreakable encryption methods, into the existing infrastructure.
Ensuring Security with Quantum Internet
Quantum internet holds the promise of implementing unbreakable encryption methods, even if future quantum computers emerge, explains Professor Dr. Michael Kues, director of the Institute of Photonics and board member of the PhoenixD talent cluster at LUH. Our research is a significant step towards combining traditional and quantum internet.
In their experiments, the researchers demonstrated that the entanglement between photons can be maintained even when transmitted together with laser pulses. We can use high-speed electrical signals to change the color of the laser pulses to match the color of the entangled photons, explains Philip Rübeling, a doctoral student researching quantum internet at the Institute of Photonics. This allows us to combine the same-colored laser pulses and entangled photons in the fiber, and then separate them after transmission.
Breaking New Ground in Optical Fiber Transmission
The research team’s groundbreaking technique enables the transmission of photons in the same color channel as the laser, making it possible to use all color channels for traditional data transmission. Entangled photons block the data channels in the fiber, making it impossible to use them for traditional data transmission, says Jan Heine, a doctoral student in the Kues research group. Our experiment demonstrates the successful application of hybrid networks.
A Milestone in Telecommunications
The discovery by the Leibniz University Hanover research team represents a significant milestone in the field of telecommunications. As the world continues to rely on traditional internet for its everyday operations, the integration of quantum internet offers a promising solution to enhance security and efficiency.
Conclusion
The fusion of quantum internet and traditional internet is a significant step forward in the field of telecommunications. The research team’s innovative technique for transmitting entangled photons through optical fibers opens the door for a more secure and efficient future. As technology continues to evolve, the integration of quantum internet into our daily lives is becoming increasingly likely, and the Leibniz University Hanover research team’s discovery is a crucial step in that direction.
