Quantum computing represents a fundamental shift from classical systems, which process data using binary bits that exist as zeros or ones in underlying codebases. Quantum machines use qubits, which possess a property called superposition -- allowing them to evaluate vast numbers of possibilities simultaneously. This capability holds particular promise for artificial intelligence (AI), where quantum computers could deliver faster answers to complex optimization problems, enhance machine learning, and simulate molecular interactions, among many other uses. According to McKinsey & Company, quantum computing could add up to $2.7 trillion of value to the global economy by 2035, underscoring the scale of the opportunity as this technology matures from laboratory curiosity toward practical utility. What are the most popular quantum computing stocks? IonQ (IONQ -3.61%), Rigetti Computing (RGTI -4.71%), and D-Wave Quantum (QBTS +0.00%) are the primary publicly traded pure-play companies focused on quantum computing hardware and services. IonQ employs trapped-ion qubits in its quantum systems, which aim to improve AI models and create better data for research purposes. Meanwhile, Rigetti uses superconducting qubits to build quantum computers that customers can leverage with existing AI-native tools. Both IonQ and Rigetti offer access to their platforms through cloud-based environments, seeking integrations with infrastructure providers like Microsoft Azure, Amazon Web Services, and Google Cloud. D-Wave has primarily focused on a niche technology called quantum annealing that is only useful for solving optimization problems and sampling problems. However, those types of problems include a host of real-world applications in areas like logistics, finance, and drug discovery. Across these companies, technology remains heavily research-oriented. While commercial systems and cloud access are expanding, they are still years away from delivering enterprise-grade fault-tolerant machines capable of providing a measurable quantum advantage.
