IET - Quantum Communication and Quantum Networks

26th April 2021 7:00 pm

When you send a message online, it stays secure because we use difficult mathematical problems to encrypt the data. But difficult does not mean impossible, so computers powerful enough can read all secure data transmitted over the internet today. Instead of using mathematical problems that are difficult, we can use processes based on the laws of physics to create mathematically perfect security. This technique is called quantum communication. I will introduce you to the basics of quantum communication and the quantum entanglement we use to implement it. I will then share my vision of how we can build a better internet – the quantum internet – and the latest advances we have made towards making it a reality.
