Researchers are building quantum internet: How this 'unhackable' network works
A significant step toward a secure and revolutionary communication network has been taken with the launch of the Integrated Quantum Networks (IQN) Hub in the UK. This groundbreaking research initiative aims to develop a "near-unhackable" quantum internet, a vast network that uses the principles of quantum mechanics to transmit information. Heriot-Watt University has been chosen to lead the IQN Hub as part of the UK government's plan to invest £160 million in quantum technologies.
Understanding bits, qubits, and entanglement
Traditional internet uses bits, either 0 or 1. Quantum networks use qubits, existing as 0, 1, or both at once. It's like a coin that's both heads and tails until you look at it. This unique state, called superposition, allows for entanglement - linked qubits sharing an outcome regardless of distance. Imagine two coins that are entangled. If one is heads, you instantly know the other coin is tails. This instantaneous connection is what makes quantum networks virtually unhackable.
Quantum internet: A solution to cybercrime and more
In an era where cybercrime costs the UK an estimated £27 billion annually, a quantum internet promises unprecedented levels of security. By using qubits and entanglement, quantum networks can create a communication system that is theoretically impossible to intercept. Any attempt to measure or intercept a qubit would disrupt its state, alerting the sender and receiver of a potential breach Beyond enhanced security, a quantum internet could revolutionize fields such as healthcare, banking, and others.
Quantum technology: A supercharged version of existing systems
Professor Gerald Buller, who will lead the IQN Hub at Heriot-Watt, described quantum technology as a supercharged version of today's technology. "It allows us to solve problems and secure data in ways that are unimaginable with conventional technology. This could lead to breakthroughs in everything from pharmaceutical research to exciting new materials development," he said. The primary focus of the IQN Hub is to create large-scale quantum networks capable of distributing quantum entanglement.
Heriot-Watt's significant role in quantum research hubs
Heriot-Watt University also plays a significant role in three of the four other newly announced quantum hubs. These include hubs focused on quantum-enabled position, navigation and timing, quantum biomedical sensing, and quantum sensing, imaging, and timing. The IQN Hub brings together a network of over 40 non-academic collaborators from startups to multinational corporations. It will receive over £20 million in partner support to help translate quantum innovations into new products and services.
Quantum hubs: A bridge between ideas and practical solutions
The five new quantum hubs are being delivered by the UKRI Engineering and Physical Sciences Research Council (EPSRC), with a £106 million investment from EPSRC and other partners. Secretary of State for Science, Innovation and Technology, Peter Kyle, stated that these hubs will bridge the gap between brilliant ideas and practical solutions. He added that they aim to transform sectors like healthcare and security while creating a culture of accelerated innovation that helps grow the economy.
