Scientists have successfully transmitted quantum data<\/strong> over standard fiber optic<\/strong> infrastructure. This innovative method could be a significant step in the development of the quantum internet<\/a><\/em><\/strong>.<\/p>\n\n\n\n

The scientific community has taken another important step in laying the foundations of the quantum internet. In a recent study published in the journal Science<\/em>, researchers succeeded in sending quantum signals<\/strong> through fiber optic cables, which are based on today’s internet infrastructure. This achievement allows quantum data<\/strong> to be transmitted in a manner compatible with classic internet protocols<\/strong>, holding great promise for the future development of the quantum internet<\/strong>.<\/p>\n\n\n\n

Liang Feng<\/strong>, a professor of materials science and electrical engineering at the University of Pennsylvania, highlights the importance of this development. Feng noted that most previous quantum communication<\/strong> experiments were limited to isolated laboratory environments or special infrastructures, but this new approach has managed to integrate quantum signals<\/strong> into real-world networks.<\/p>\n\n\n\n

The team led by Feng developed a specialized quantum chip<\/strong> called the Q-Chip<\/strong>. This chip carries quantum data<\/strong> over the same fiber optic cables as classic signals<\/strong>, and this process is carried out in a way that is compliant with standard internet protocols.<\/p>\n\n\n\n

Unlike the bits that are the fundamental data carriers of classic computers, quantum computers<\/strong> process data using qubits<\/strong>, which can exist in multiple states simultaneously. The entanglement<\/strong> relationship that qubits establish with each other allows data to remain connected regardless of distance. However, this property also makes quantum data<\/strong> extremely sensitive and fragile. Quantum data<\/strong> can collapse the moment it is observed, and the information being carried can be lost.<\/p>\n\n\n\n

While the current internet infrastructure uses routers<\/strong> to direct data packets, operating in the same way with quantum data<\/strong> could destroy this delicate information. This is where the Q-Chip<\/strong> comes into play.<\/p>\n\n\n\n

The Q-Chip<\/strong> solves this problem by adding a classic “header”<\/strong> to every quantum signal<\/strong>. The header, encoded by fiber optic laser pulses, contains information about the data’s routing and timing. Routers<\/strong> read this header and direct the data to the correct destination, but they do not interfere with the quantum signal<\/strong>. Thus, the quantum<\/strong> and classic signals<\/strong> are transmitted simultaneously, synchronized, and over the same fiber optic<\/strong> cable. Feng describes this technology as “a huge step for transmitting quantum signals<\/strong> without degradation over existing infrastructures.”<\/p>\n\n\n\n

To test the developed system, the team used a one-kilometer fiber optic line<\/strong> owned by Verizon. The quantum signal<\/strong> reacted to environmental noise in a way similar to the classic signal<\/strong>. In this case, the degraded signal was corrected with the help of the classic signal<\/strong>, and the quantum data<\/strong> was safely delivered to its destination. This test demonstrates that it is possible to transmit quantum data<\/strong> in a manner compatible with existing infrastructures.<\/p>\n\n\n\n

Further stages of the work reveal that the Q-Chip<\/strong>‘s silicon-based structure<\/strong> will facilitate mass production using existing manufacturing processes. Feng states that this technology is a foundational step to launch the first phases of the quantum internet<\/strong> in local<\/strong> and metropolitan-scale networks<\/strong>.<\/p>\n\n\n\n
