Hannover, Germany – A groundbreaking discovery by researchers at Leibniz University Hannover has paved the way for the integration of quantum internet with traditional internet, potentially enhancing security and maximizing the use of existing infrastructure.
The research team, based at the Institute of Photonics at Leibniz University Hannover, has developed an innovative transmission and reception system that allows for the transmission of entangled photons through optical fibers. This breakthrough enables the next-generation telecommunications technology, quantum internet, to be transmitted through optical fibers, offering a highly secure encryption method that even future quantum computers cannot decipher, ensuring the safety of critical infrastructure.
The researchers have demonstrated that even when entangled photons are sent together with laser pulses, their entanglement is maintained. To realize quantum internet, we need to transmit entangled photons through optical fiber networks, said Professor Dr. Michael Kues, director of the Institute of Photonics and board member of the PhoenixD talent cluster. We also hope to continue using optical fibers for traditional data transmission. Our research is an important step towards combining traditional internet with quantum internet.
In their experiments, the researchers were able to change the color of laser pulses using high-speed electrical signals, making them match the color of entangled photons. This effect allowed them to emit laser pulses and entangled photons of the same color into the optical fiber and then separate them after transmission.
This effect enables the integration of traditional internet with quantum internet, said Jan Heine, a doctoral student studying quantum internet at the Institute of Photonics. Until now, it has been impossible to use two colors of transmission in a single optical fiber.
The researchers have shown for the first time that photons can now be sent in the same color channel as laser pulses. This means that all color channels are still available for traditional data transmission. Our experiment demonstrates the success of the practical application of hybrid networks, said Professor Kues.
The breakthrough could have significant implications for the future of telecommunications. Quantum internet offers a highly secure encryption method, making it ideal for transmitting sensitive information. By combining quantum internet with traditional internet, it is possible to enhance the security of existing networks while also maximizing the use of existing infrastructure.
The researchers are now working on further developing the technology to improve its efficiency and scalability. With continued advancements, quantum internet could become a key component of the future telecommunications landscape, offering a more secure and efficient way to transmit data.
In conclusion, the groundbreaking discovery by researchers at Leibniz University Hannover marks a significant milestone in the development of quantum internet. By combining quantum internet with traditional internet, the researchers have opened the door to a more secure and efficient future for telecommunications.
