Textbook in PDF format

The rise of nanotechnology has led to an increasing role for quantum computing in the development of smaller and more energy-efficient computers. By leveraging the principles of quantum mechanics, certain computations can be performed at significantly higher speeds. Quantum computing represents one of the most promising nanotechnologies for creating modern and compact computer systems.
Unlike traditional computers that rely on binary logic, quantum computers operate on a fundamentally different concept. They exploit quantum entanglement to simultaneously evaluate multiple probabilities. The processing and memory unit of a quantum computer system is becoming small like an atom and the switching techniques have reached the peak of their development. Consequently, a completely fresh mindset is needed for constructing computing machines. Recently, advance ments in mathematics, materials science, and computer engineering have brought quantum computing from the realm of theory into practical implementation.
This quantum computing book covers basic themes of quantum computing in the first part, fault-tolerant quantum computing in the second part, quantum-dot cellular automata (QCA) in the third part and QCA fault-tolerant circuits in the fourth part. Each part has a critical thinking question section for the readers.
