In the heart of Tehran, researchers are pushing the boundaries of quantum communication, and their work could revolutionize the energy sector’s approach to secure, high-speed data transmission. Marzieh Bathaee, a leading figure at the Sharif Quantum Center, Sharif University of Technology, is at the forefront of this cutting-edge research. Her latest study, published in the IEEE Transactions on Quantum Engineering (translated from Persian as IEEE Transactions on Quantum Engineering), explores how existing communication infrastructure can be leveraged to create a cost-effective global quantum Internet.
Bathaee and her team are focusing on the quantum versions of conventional wavelength-division-multiplexing and multiple-access (WDM) communication systems. These systems are the backbone of modern fiber-optic networks, enabling high-speed data transmission by splitting a single optical fiber into multiple virtual fibers, each carrying a different wavelength of light. By applying quantum principles to these systems, the researchers aim to enhance security and efficiency, which could have significant implications for the energy sector.
One of the key aspects of their research is the use of quantum states of light, such as coherent (Glauber) and number (Fock) states. These quantum states allow for the creation of secure communication channels that are virtually immune to eavesdropping. “By employing quantum single-photon sources and exclusive quantum results, we can study and harness quantum correlations occurring in the receivers’ states,” Bathaee explains. This means that any attempt to intercept the data would inevitably alter the quantum states, alerting the communicating parties to the presence of an intruder.
The researchers have also developed quantum routers based on waveguide grating routers and fiber-to-the-quantum nodes. These innovations could enable the creation of all-quantum networks, where every node in the network operates on quantum principles. This would allow for the secure and efficient transmission of data over vast distances, a crucial requirement for the energy sector, where data from remote sensors and devices needs to be transmitted securely and reliably.
One of the most promising applications of this research is in quantum key distribution (QKD). QKD allows two parties to generate a shared, secret key that can be used to encrypt and decrypt messages. The security of QKD is based on the principles of quantum mechanics, making it virtually impossible to intercept the key without detection. Bathaee’s research has shown that waveguide grating router-based QKD networks can achieve a higher rate of secure keys compared to traditional Lambdanet-based networks.
The potential commercial impacts of this research are immense. In the energy sector, secure and efficient data transmission is crucial for the operation of smart grids, renewable energy integration, and remote monitoring of assets. Quantum communication systems could provide the necessary security and efficiency, enabling the energy sector to operate more reliably and sustainably.
As Bathaee and her team continue to push the boundaries of quantum communication, the future of the energy sector’s data transmission looks increasingly secure and efficient. Their work, published in the IEEE Transactions on Quantum Engineering, is a significant step towards the realization of a global quantum Internet, and its implications for the energy sector are profound. The energy sector should keep a close eye on these developments, as they could shape the future of secure and efficient data transmission in the industry.
