Abstract Quantum computing has generated splashy headlines with pronouncements of “quantum supremacy”, but the reality is much more complicated than simple headlines can capture. Quantum computers are designed to use the interactions between quantum objects, such as electron spins, to perform useful computations. This paper will provide an overview of some of the engineering challenges involved in developing quantum computers and highlight some potential applications of interest to the mechanical engineering community. These challenges include the need to isolate the quantum bits — the logic elements used in quantum computers — from the environment to protect them from external sources of noise. In some quantum computer designs, this requires cooling the quantum bits to temperatures below 1 degree Kelvin, which requires specialized refrigeration systems. Potential future applications of quantum computers, particularly for mechanical engineers, rely on the promise of increased computational power for solving complex problems that have many degrees of freedom. This includes solving large systems of equations for finite element analysis and computational fluid dynamics, and in computational chemistry for materials optimization. Quantum computing is clearly a future technology — more development is needed before it will be used for engineering applications. That said, there are clear potential applications in mechanical engineering, and it will be a future technology that will be used for engineering analysis-based design optimization, digital twin development, and other relevant applications.

ABSTRACT Quantum computing represents a fundamental shift in the way computational problems are approached and solved. Unlike classical computing systems that rely on binary bits to process information, quantum computing utilizes quantum bits, or qubits, which exploit principles of quantum mechanics such as superposition and entanglement. This transition from classical bits to qubits has opened new possibilities for solving complex problems that are computationally infeasible for traditional systems. This paper explores the evolution of computing paradigms from classical architectures to quantum-based models, highlighting the theoretical foundations and technological advancements that have driven this transformation. It discusses the core concepts of quantum computing, including qubit representation, quantum gates, and computational models, along with an overview of current quantum hardware architectures. Furthermore, the paper examines key application areas such as cryptography, optimization, artificial intelligence, and scientific simulations, where quantum computing demonstrates significant potential. Despite its promise, quantum computing faces substantial challenges related to hardware stability, error correction, scalability, and resource requirements, which are also analyzed. Finally, the paper outlines future research directions and the potential impact of quantum computing on next-generation information processing systems, emphasizing its role in redefining the boundaries of modern computation.
