Jakarta –
The researchers managed to use Q-Chip to send quantum data through standard fiber using the Internet Protocol (IP). This also shows the quantum internet is in sight.
Unlike the current conventional internet, quantum internet uses Qubit which can be in superposition 0 and 1, and connects particles across distances through attachment. Meanwhile, the internet is currently transmitting data using a bit in the form of 0 or 1 numbers, which depends on electrical or optical signals.
Quantum internet is referred to as a future communication network and its existence does not replace the internet today, but rather provides a higher level of security.

In a study published on August 28 in the journal Science, researchers used quantum chips made specifically to package quantum data with standard optical signals and send them through commercial infrastructure.
This breakthrough marked the first time quantum data was sent using the Internet Protocol (IP), the same standard of communication that underlies the current wide ribbon network. The results show that quantum communication can run on existing networks, without requiring special infrastructure.
“Unlike previous experiments that require isolated laboratory settings or special infrastructure, this approach integrates quantum communication into real world networks for the first time,” said Senior Feng Study Author, Professor of Material and Electrical Engineering at the University of Pennsylvania, to Live Science was quoted on Saturday (27/9/2025).
“Our Q-Chip allows the control of quantum signals and classic signals, so that both of them run together through the same optical fiber cable, using a standard internet protocol,” he added.
Why is an important quantum internet
Previously, sending quantum data requires special paths or separate infrastructure. With Q -Chip, quantum internet can run on an existing optical fiber network – cut big obstacles in this technology adoption.
The experimental team tested this chip using an optical fiber along about 1 kilometer belonging to the Verizon telecommunications operator. They show that despite environmental noise, quantum signals are still acceptable without damage with the help of classic signals that “help correction.”
Researchers estimate that in the next 5-10 years, local scale or city quantum internet will begin to emerge. Potential applications include: ultra-security communication, connections between quantum computers, and very precise distributed sensor systems-for example navigation and ultra-accurate timing.
With progress such as Q-Chip, a quantum network that used to be only a scientific dream is now increasingly apparent. Quantum Internet promises speed, security, and capabilities that far exceed the classic system – signals that cannot be tapped without detected, ultra -low latency, and the potential for new applications that cannot be reached by the current system.
