Quantum entanglement offers unprecedented precision for GPS and more
Your phone’s GPS, the Wi-Fi in your house and communications on aircraft are all powered by radio-frequency, or RF, waves, which carry information from a transmitter at one point to a sensor at another. The sensors interpret this information in different ways. For example, a GPS sensor uses the angle at which it receives an RF wave to determine its own…
A better starting point for exploring entanglement
Quantum entanglement is perhaps one of the most intriguing phenomena known to physics. It describes how the fates of multiple particles can become entwined, even when separated by vast distances. Importantly, the probability distributions needed to define the quantum states of these particles deviate from the bell-shaped, or ‘Gaussian’ curves which underly many natural processes. Non-Gaussian curves don’t apply to quantum…
A spookily good sensor
Scientists from the Research Center for Advanced Science and Technology (RCAST) at The University of Tokyo demonstrated a method for coupling a magnetic sphere with a sensor via the strange power of quantum entanglement. They showed that the existence of even a single magnetic excitation in the sphere could be detected with a one-shot measurement. This work represents a major advancement…
How supercomputers are helping us link quantum entanglement to cold coffee
Theoretical physicists from Trinity College Dublin have found a deep link between one of the most striking features of quantum mechanics—quantum entanglement—and thermalisation, which is the process in which something comes into thermal equilibrium with its surroundings. …
What is space-time? The true origins of the fabric of reality
A bold new perspective suggests space-time isn’t a fundamental entity but emerges from quantum entanglement, says physicist Sean Carroll Source: https://www.newscientist.com/article/mg24332470-500-what-is-space-time-the-true-origins-of-the-fabric-of-reality/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Researchers develop practical method for measuring quantum entanglement
Rochester Institute of Technology researchers have helped develop a new technique for quantifying entanglement that has major implications for developing the next generation of technology in computing, simulation, secure communication and other fields. The researchers outlined their new method for measuring entanglement in a recent Nature Communications article. …
World’s first link layer protocol brings quantum internet closer to a reality
Researchers from QuTech have achieved a world’s first in quantum internet technology. A team led by Professor Stephanie Wehner has developed a so-called link layer protocol that brings the phenomenon of quantum entanglement from experimental physics to a real-world quantum network. This brings closer the day when quantum internet can become a reality, delivering applications that are impossible to achieve via…
Quantum entanglement in chemical reactions? Now there’s a way to find out
Scientists have long suspected that a quantum phenomenon might play a role in photosynthesis and other chemical reactions of nature, but don’t know for sure because such a phenomenon is so difficult to identify. …
