Are We Inching Closer to Quantum Internet?

When the precursor to today’s internet carried its first message in 1969, clunky but functional classical computers had already been around for decades. Now, physicists are designing the embryonic threads of a whole new internet for moving and manipulating a radically different type of information: the quantum bit, or “qubit.” And this time, they aren’t waiting for the corresponding computers to exist first. Two teams have now demonstrated an ensemble of technologies essential to building the backbone of such a network — devices known as quantum repeaters. The researchers managed, for the first time, to use light particles to bind … Read more

The advent of mass working from home has made many people more aware of the security risks of sending sensitive information via the internet. The best we can do at the moment is make it difficult to intercept and hack your messages — but we can’t make it impossible. What we need is a new type of internet: the quantum internet. In this version of the global network, data is secure, connections are private and your worries about information being intercepted are a thing of the past. My colleagues and I have just made a breakthrough, published in Science Advances, … Read more
