Quantum computers are expected to far surpass the capabilities of today's most powerful supercomputers, particularly in areas such as the theoretical simulation of quantum systems, cryptography, and information processing.
The cluster state is a special, highly entangled quantum state that forms the universal resource on which measurement-based quantum computation can be performed.
This paper provides a brief review of the theoretical foundations of cluster state quantum computation
and how it evolved from the traditional model of digital computers. It then proposes a scheme for
the generation of such entanglement in a solid-state medium through the suppression of resonant
tunneling of a ballistic electron by a single-electron charge qubit. To investigate the viability of
the scheme for the creation of cluster states, numerical calculations are performed in which the
entanglement interaction is modeled in detail.
