Abstract

One of the available methods for building a quantum computer involves the use of the concept of NMR. This concept is based on the molecules’ nuclei spin states considered as qubits, and this technology utilizes a group of atoms, molecules, or even macromolecules. It is noted MRI and NMR have applications in the fields of chemistry, physics, molecular biology, and medicine. Moreover, quantum computers similar NMR utilizes molecules in which some of the atoms have nuclei behaving like spin systems. In addition, each nucleus has various energy levels, indicating different qubits. In this computational method, logical gates, including the CNOT, will play an integral role. The nanoscale NMR device is capable of demonstrating the characteristics of molecules, macromolecules, and cells in a non-invasive fashion, i.e., it can indicate the position of atoms without destroying them. This will significantly contribute to our understanding of molecules, macromolecules, and living cells. On the other hand, qubits are quantum sensors with a high sensitivity in order to be used for imaging a biomolecule. Hence, identifying the building of biological molecules can be highly important.
