According to a report by number crunchers GlobalData the technology will transform various sectors, including telecommunications, cybersecurity, and computing,

GlobalData Practice Head of Disruptive Tech Kiran Raj said the quantum internet will tackle essential challenges across numerous industries. For example, in telecommunications, it reduces latency and increases bandwidth, addressing significant constraints.

He said: “In the realm of cybersecurity, it introduces inviolable encryption techniques such as quantum key distribution (QKD) to protect confidential data. Regarding computing, it enables groundbreaking quantum algorithms, enhancing computational power and efficiency, especially in fields like cryptography, optimisation, and intricate simulations. Essentially, the quantum internet is anticipated to become a pivotal element for future industrial progress."

GlobalData Disruptive Tech Project Manager Saurabh Daga said that while the quantum internet has primarily been an experimental notion, recent scientific breakthroughs, coupled with parallel progress in quantum computing, are cementing its trajectory towards complete practical application and eventual market introduction.

“These developments signify a considerable step in incorporating the quantum internet into practical uses, marking a notable landmark in its evolution from concept to reality."

GlobalData's Disruptor Intelligence Center has been watching the following companies which it thinks will kick the whole thing off.

• Aliro Quantum's AliroNet Solution: The American startup Aliro Quantum has unveiled AliroNet, a comprehensive entanglement-based quantum network solution. AliroNet simulates quantum networks, conducts small-scale trials, and implements extensive networks, revolutionising sectors like government, defence, finance, research, and environmental sciences with secure communications and distributed quantum sensing.
• Cisco’s Project Lyra: In collaboration with UK-based Nu Quantum and supported by UK Research and Innovation, Cisco is working on Lyra to develop a modular quantum network infrastructure for a prototype quantum data centre. By merging quantum technology with standard networking, they aim to create scalable data centres, propelling Cisco's future networking technologies.
• QphoX's Quantum Modem Technology: The Dutch startup QphoX has created a quantum modem to expand quantum computers and establish a quantum internet. This technology facilitates secure, efficient data transfer over vast distances by converting quantum information between microwave and optical domains, fostering interconnected quantum systems.

• EPB’s Quantum Infrastructure: The Electric Power Board of Chattanooga (EPB) and Qubitekk have initiated a commercial quantum network that merges EPB's broadband proficiency with Qubitekk's quantum encryption technology. This network enables secure, rapid communication for sectors such as finance, healthcare, and government.

Daga said that the challenges persist in expanding quantum networks and ensuring their compatibility with current systems.

“Overcoming these hurdles is vital for fully capitalising on the quantum internet's advantages. As the technology matures, collaboration between industrial and academic entities will be crucial for the global deployment of quantum internet infrastructure, spurring innovation and economic development."
