Chapter 7 Quantum processors/networks/sensors

The concept of quantum computing was introduced to make processing faster so that processes can run in parallel. It harnesses the law of quantum mechanics that aids in solving highly complex problems. The law incorporates the concept of superposition and entanglement, which are the primary properties of quantum. The qubits are those involved in quantum, with the feasibility that a bit can represent any of the two states, unlike classical computers. With the advent of the new technology, it is important to enhance the other units that support in building up the technology of the future. This chapter proposes the different aspects involved in quantum computing, such as quantum sensors, the processing of quantum, the networks established, etc. It also emphasizes on the importance of moving from the classical computers to quantum, with comparisons. The focus is on knowing that there is the possibility of quantum computing in solving problems that cannot be solved in polynomial time. All these aid in uplifting the classic computing power to quantum. As it is understood that this technology is still in the research stage, the chapter provides information on what it is to actually build a quantum system. Having a brief idea on the different units, it also identifies the different applications of quantum with a few case studies.
