Classical computers have been present for a long time and they have played a significant role in scientific advancements. Quantum computing has shown good results in solving complex problems. Quantum computers use phenomena of quantum superposition and quantum entanglement to form states that scale exponentially with the number of qubits or quantum bits [1]. Classical computers use individual bits, 0 and 1 to store information as binary data & quantum computers use the probability of state before it is measured [2]. Therefore, it gives them a potential to process exponentially more data as compared to classical computers. Unlike classical computers that use binary bits, quantum computers use qubits that are produced by quantum state of object to perform operations. Since, these qubits are quantum, they follow phenomena like quantum superposition and entanglement. Superposition is ability of a quantum system to be in multiple states at the same time. Entanglement is the strong correlation among quantum particles. These phenomena help quantum computers work with 0, 1 and superposition of 0 and 1, giving it advantage of doing complex calculations that classical systems cannot do or take a significant amount of time to get desired results [3]. Quantum computing is used because of its potential for changing time and space complexity of many algorithms we have been using as a solution to linear system of equations [4]. Quantum simulation is one of the most prominent areas of quantum computers, it has the potential to solve the complexities of molecular and chemical interactions which can lead to the discovery of new medicines and materials. Various applications of quantum computing in several significant areas of computer science, such as cryptography, machine learning, deep learning and quantum simulations. They also use various real-life scenarios such as risk analysis, logistics and satellite communication [6].

Quantum computing represents a revolutionary leap in computational power, leveraging the principles of quantum mechanics to process information in fundamentally new ways. Unlike classical computers, which use bits to represent data as 0s or 1s, quantum computers use quantum bits or qubits, enabling the phenomena of superposition and entanglement to perform complex calculations more efficiently (Nielsen & Chuang, 2010). This article explores the basic principles of quantum computing, the different models and algorithms that have been developed, and the current state of quantum hardware. The power of quantum computing lies in its ability to solve certain types of problems exponentially faster than classical computers. For instance, Shor's algorithm can factorize large integers in polynomial time, posing a significant threat to classical encryption methods (Shor, 1997). Similarly, Grover's algorithm provides a quadratic speedup for unstructured search problems, showcasing the potential for dramatic improvements in database search capabilities (Grover, 1996). These algorithms exemplify how quantum computing can revolutionize fields that rely on complex computations. Quantum hardware, however, is still in its nascent stage, with significant challenges to be overcome. Current quantum computers, such as those developed by IBM and Google, have demonstrated quantum supremacy but are limited by issues of qubit coherence and error rates (Arute et al., 2019). Quantum error correction and the development of more stable qubit technologies are critical areas of ongoing research (Preskill, 2018). Despite these challenges, recent advancements in quantum hardware and algorithms continue to drive the field forward, promising transformative impacts on industries such as cryptography, drug discovery, and artificial intelligence. As quantum computing continues to advance, it holds the promise of solving problems that are currently intractable for classical computers, paving the way for unprecedented technological and scientific advancements (Shor, 1997; Grover, 1996). This article provides a comprehensive overview of the current landscape of quantum computing, discussing its foundational principles, key algorithms, hardware challenges, and potential applications. By understanding these aspects, we can better appreciate the profound implications of quantum computing for the future of technology and science.
