IS YOUR PASSWORD IN DANGER? Demystifying What Quantum Computers Can and Cannot Do

Quantum mechanics has been one of the most successful theories in physics governing mostly the behavior of the very small and the very cold, and is becoming more and more relevant in society through applications like quantum computing. With government initiatives like the National Quantum Initiative and companies like Google claiming quantum supremacy, what is all this hype about? Join us in demystifying quantum mechanics and quantum computing and find out whether your password could be in danger! Speaker Kenneth Wang received his Bachelor of Arts in Chemistry and Physics from Harvard College in 2017. He is currently pursuing a PhD in Physics still at Harvard, working in the lab of Kang-Kuen Ni. His research focuses on physical implementations of quantum computers, specifically using ultracold atoms and molecules. Glossary of Important Terms Wave-particle duality: A concept forming one of the foundations of quantum mechanics, where particles can behave like waves and vice-versa. Photon: A particle of light, whose energy is related to the frequency of the light. Interference: A property of waves where multiple waves add together. Superposition: Classically, the principle that results in interference. Quantum mechanically, the idea of a single particle being in multiple states at the same time. Wavefunction: The quantum description of a particle. The amplitude squared of a component of the wave function is the probability of finding the particle in that state. Measurement: The concept of observing a quantum system. A measurement is how information is extracted from a quantum system, and the result of the measurement changes the state of the system. Spin: An intrinsic property of a particle like charge or mass. Spins interact with magnetic fields, and can only take a discrete set of values. Bit: The fundamental unit of computing, which can be either 0 or 1. Logic Gate: The process of performing a logical operation on one or more bits. They form the basis of algorithms. Algorithm: A procedure to solve a particular problem. Qubit: The quantum version of the bit, which can importantly be 0 and 1 at the same time. Encryption: A method to securely send information from one party to another. Superconductor: A material with zero resistance, thus allowing the transfer of electrical energy with 100% efficiency Resources to learn more Video from Hitachi demonstrating the electron double-slit diffraction experiment:    • Interference pattern (with narration) - Hi...   SITN seminar on laser cooling and using ultracold molecules as a quantum computer:    • Physics -- but cooler!: Taming quantum mec...
