The Basics of Quantum Computing in Two Pages

Take it for what its worth. There may be more succinct explanations out there, but this is an example of what *is *out there. Much work to do at this early stage in the quantum computing era. Qubit.

+ **Superposition** is the ability of a quantum system to be in multiple states simultaneously. The go-to example of superposition is the flip of a coin, which consistently lands as heads or tails—a very binary concept. However, when that coin is in mid-air, it is both heads and tails and until it lands, heads and tails simultaneously. Before measurement, the electron exists in quantum superposition.

*The basic properties of quantum computing are superposition, entanglement, and interference. *

+ **Entanglement** as a quantum property is taking objects and connecting them by permanently entangling them together. When adding an additional qubit to a quantum computer, a 50-cubit quantum machine can examine two to the power of 50 states simultaneously. The increase in power plus the entanglement of qubits allows quantum computers to solve problems efficiently, finding a solution faster, with many fewer

+ **Interference** can be used to control quantum states and amplify the signals that are leading toward the right answer, while canceling signals that are leading to the wrong answer.
