Can Quantum Sensors Replace GPS? How Atom Interferometers Navigate Without Satellites
Quantum accelerometers and atom interferometers could help vehicles navigate when GPS is unavailable. Here is what quantum navigation can—and cannot—do.
31 Quantum Physics Terms I Wish Someone Had Explained to Me Sooner
Spoiler: by the end, you’ll see that the quantum world is less like a terrifying math monster and more like a mischievous cat that refuses to stay in one box. 1. Quantum The VIP prefix itself! “Quantum” simply means the smallest possible chunk of something—energy, light, even information. 2. Superposition A quantum object can hang…
Quantum Tunneling Composite (QTC): How Pressure Sensors Work
What is a quantum tunnelling composite (QTC)? It is a pressure-sensitive material made from an insulating, flexible polymer containing conductive particles, often nickel. Unpressed, the particles remain electrically separated; when the material is squeezed, tiny gaps narrow and electrons can tunnel between particles, causing a large drop in electrical resistance. QTC material is therefore useful…
Measuring Earth’s Rotation with Quantum Entanglement
Measuring Earth’s Rotation with Quantum Entanglement: A Quantum Leap For over a century, scientists have used devices called interferometers to measure Earth’s rotation. Now, researchers at the University of Vienna have taken this a step further by using quantum entangled light particles, known as photons, to achieve the most precise measurement yet. Their groundbreaking experiment,…
