Quantum Mechanics in your Smartphone
The Engineering Puzzle of Storing Trillions of Bits in your Smartphone / SSD using Quantum Mechanics
It’s a puzzle as to how your smartphone or the solid-state drive in your laptop can store gigabytes to terabytes of data by the click of a button! It’s amazing that your devices work flawlessly, and the information doesn’t leak out. In this video, we’ll learn how scientists and engineers use quantum mechanics to store this information reliably. We’ll take a look on the inside of the 3D NAND technology, and see an application of quantum mechanics- specifically quantum tunneling.
