Abstract In recent studies, quantum computing has turned out as a new paradigm of computation and has been able to solve the problems with many classes of problems that are still unsolvable by ordinary classical machines. In contrast to the commutative architecture of binary computing, which needs bits being limited to either zero or one, quantum computing utilizes superposition, entanglement and unitary evolution, which permit computations on exponentially large spaces. This article provides a systematic coverage of the literal principles, quantum mathematical procedures, computer tumult, and the recent applications of the quantum technologies. It further examines the constraints of Noisy Intermediate-Scale Quantum (NISQ) devices and explains the possible ways that could be taken to achieve scalable, fault-tolerant architecture. The review highlights the importance of continuous interdisciplinary cooperation between physics, engineering, and computer science solutions that make quantum computing a feasible idea.
