Quantum computations are conducted by the continuous adaptation of quantum systems. This chapter provides a description of the nonclassical behavior of entangled states during measurement using the traditional method for measuring multiple-qubit devices. It also provides a short overview of the types of transformations that may be applied to generic quantum systems. The chapter shows an example of standard-based measurements of a single qubit. It presents a comprehensive analysis of the unitarity criterion and the no-cloning condition as they apply to changes in quantum states. The chapter focuses on n-qubit systems and defines the fundamental building elements of a conventional circuit model for quantum computing. It examines subsystems of larger subatomic particles, such as those found in open quantum systems, to learn more about the effects of modifications made to the larger systems on the smaller systems.
