# qubit

## Definitions

### General Science

### Electronics

- Abbreviation of quantum bit. An individual particle utilized to store information. Particles, which obey the laws of
__quantum mechanics__, can have their __spin__ influenced for __storage__, and detected for retrieval. A single qubit can be used to represent a one, a __zero__, or both, with a coefficient representing the probability for each __state__. Two qubits can represent every two-bit __number__, which specifically are 00, 01, 10, and 11. Each additional qubit increases the number representation exponentially, at a rate of 2^{n}, where *n* is the number of qubits. For example, 50 qubits can represent every number between zero and beyond a __quadrillion__. - synonymquantum bit
