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.

The basics of quantum computing—A tutorial

Selected notes ~

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.
