Quantum computing

“

- In this lesson, we're going to discuss quantum computing and nanotechnology. First, let's start with quantum computing, which is the combination of physics, mathematics, and quantum mechanics to exploit the collective properties of quantum states, such as the superposition, interference, and entanglement to perform computation. Now, a quantum is the smallest possible discrete unit of any physical property, such as an atomic or subatomic particle. Whereas a binary digit or bit is stored as a one or a zero that represents an on and off in a transistor, quantum computing relies on a qubit instead. Now, a cubit is a quantum bit, and instead of holding just the value of one or zero, it can hold a superposition of all the possible states or combinations. Because of this superposition that creates multiple values at once, quantum computers are much faster and more adept at solving extremely complex mathematical problems like those that we use in cryptography. This is because a quantum…
