▾Quantum technologies are slowly becoming a reality. They will likely replace GPS
Quantum technologies are relentlessly approaching and promise to revolutionize many areas. Quantum internet and quantum compasses are within our reach. A future without hackers and GPS may become a reality sooner than we think. However, scientists still face numerous obstacles, overcoming which may not be straightforward.
Quantum physics opens doors to a world of unprecedented possibilities, and scientists are racing to find its practical applications. It seems that the areas where quantum technologies will soon enter history will be the internet and possibly navigation.
Quantum internet: The unhackable network of the future?
Imagine an internet that is practically unhackable and opens doors to unprecedented computational power. This is the promise of the concept of quantum internet, which is slowly but surely becoming a reality.
Scientists from Leibniz University in Hanover conducted an experiment that could signify a breakthrough in connecting quantum technologies with existing internet infrastructure. They managed to send quantum information and classic data in the form of ones and zeros through a single optical fiber.
The key to success is the use of a special technique that allows shifting the phase of signals within the optical fiber. As a result, both quantum and classical data exist on the same frequency channel without interfering with each other.
Although this experiment is a significant step forward, the quantum internet still faces challenges. For instance, scientists are trying to extend the distance over which quantum information can be transferred without loss and are exploring ways to manage traffic in existing networks.
Quantum compasses: Goodbye GPS?
Navigation without GPS? This could also soon become a reality thanks to quantum compasses. These devices use quantum phenomena to determine position and promise independence from satellites.
Researchers from Sandia National Laboratory have made significant progress in miniaturizing the laser system essential for the functioning of quantum compasses. Specifically, they managed to shrink a system the size of a refrigerator into a miniature chip.
Quantum compasses operate on the principle of atomic interferometry. This utilizes the wave properties of atoms to measure acceleration, rotation, and angular velocity. These quantities then allow for determining the position without the need for satellite communication.
Although miniature quantum compasses are not yet ready for mass production, scientists are not giving up. They are working on miniaturizing other components and integrating them into a single chip. In the future, quantum compasses could find applications in areas where GPS is unavailable, such as densely built cities or even underwater.
Internet via light or how does Li-Fi work?
With the growing number of connected devices and the increased volume of data being transmitted, new ways are being sought to speed up and improve network efficiency. Internet via light, referred to as Li-Fi technology, uses LED lighting for wireless data transmission and promises higher speed and greater security. Let's see how it works and where it's already being tested.
What will 6G internet bring – lightning-fast connection, smart cities, and artificial intelligence in the network
Mobile networks of the sixth generation will push the boundaries of communication and data transmission. 6G internet will offer speeds in the order of terabits, minimal delay, and integration with artificial intelligence. In the article, we explain how this technology works, how it differs from 5G, what frequencies it uses, and why it is essential for smart cities and modern industry.
Wireless charging: What are its benefits, limitations, and where is it heading?
Wireless charging has evolved from a luxury feature to a standard part of most modern phones. Simply place your mobile on the pad, and energy begins to flow without searching for a cable and connector. We explain how wireless charging works, what it entails, and why Qi and Qi2 technologies have become the new standard of convenience.
What is Wi-Fi 7? What changes does it bring and when does it make sense to switch
Today's home Wi-Fi network is under increasing pressure. It has to handle video calls, online gaming, and dozens of smart devices. The new Wi-Fi 7 standard offers a solution that takes wireless connectivity to the next level. We'll explain what this standard means in practice and why it might be crucial for the future of home and business networks.
What is DNS? Everything you need to know about its functionality and setup
When you type a website address into the browser, the correct page loads in an instant. This is managed by the DNS system, without which the internet as we know it would not exist at all. In this article, you will learn what DNS is, how it works, what types of records it contains, and why it is important for both speed and security of the connection.
How does fiber optic internet work and what do you need for its installation?
Fast and stable connection is a basic necessity in every household today. The solution is fiber optic internet, which works differently than regular cables and offers greater reliability to users. We'll explain how this technology works in practice, what it entails to run a fiber optic cable to your home, and what equipment you’ll need to keep everything running smoothly.
