German Researchers Develop Technique for Fiber-Optic Transmission of Entangled Photons
In a groundbreaking discovery, researchers at Leibniz University Hannover have developed a technique for transmitting entangled photons through fiber optics, paving the way for the integration of quantum internet with traditional internet. This advancement holds the promise of enhanced security and efficient utilization of existing infrastructure.
Innovative System for Fiber-Optic Transmission of Entangled Photons
The research team, consisting of four members from the Institute of Photonics at Leibniz University Hannover, developed an innovative发射接收系统 for transmitting entangled photons through fiber optics. This breakthrough enables the next-generation telecommunications technology—quantum internet—to be transmitted through fiber optics.
Quantum Internet Offers Unhackable Encryption
Quantum internet is expected to implement unhackable encryption methods, even if future quantum computers cannot decipher them. This ensures the security of critical infrastructure.
Experiment Demonstrates Successful Integration of Traditional and Quantum Internet
In their experiments, researchers demonstrated that the entanglement between photons can be maintained even when transmitted along with laser pulses. By using high-speed electrical signals to change the color of laser pulses to match that of entangled photons, researchers were able to combine the same-colored laser pulses and entangled photons in the fiber optic cable and then separate them upon transmission.
Eliminating the Need for Separate Channels for Traditional Data Transmission
This groundbreaking technique eliminates the need for separate channels for traditional data transmission. Until now, it was impossible to use two colors of transmission in a single fiber optic cable. Entangled photons block the data channels in the fiber optic cable, making it impossible to use them for traditional data transmission, explained Jan Heine, a doctoral student in the Kues research group.
Successful Demonstration of Hybrid Network Applications
With the first demonstration of this concept, photons can now be transmitted in the same color channel as lasers. This means that all color channels can still be used for traditional data transmission. Our experiment shows that the practical application of a hybrid network can be successful, said Professor Michael Kues.
Potential Impact of the Discovery
The discovery has the potential to revolutionize the way we transmit data and ensure the security of our critical infrastructure. By combining quantum internet with traditional internet, we can achieve a more secure and efficient network that can adapt to the challenges of the future.
Conclusion
The groundbreaking discovery by researchers at Leibniz University Hannover marks a significant milestone in the development of quantum internet. By enabling the transmission of entangled photons through fiber optics, this discovery paves the way for a more secure and efficient network that can adapt to the challenges of the future.
