quantum bit

n.
The smallest unit of information in a quantum computer, existing in a superposition of two states (1 and 0), and settling on one state or the other only when a measurement of the state is made in order to retrieve the output of the computation. Also called qubit.

The main procedure of SVM parameters optimization can be described as follows: according to the variation ranges of kernel function parameter and penalty factor, constructing chromosomal genes with quantum bit coding system, so the evolutionary population which includes several chromosomes can be generated.
Quantum computing on a small scale using trapped ions (charged atoms) is carried out by aligning individual laser beams onto individual ions with each ion forming a quantum bit. However, a large-scale quantum computer would need billions of quantum bits, therefore requiring billions of precisely aligned lasers, one for each ion.
