Scalability is a key concern in large-scale quantum systems. While quantum computers have achieved impressive milestones, such as achieving quantum supremacy, they still have a limited number of qubits. Scaling quantum processors to handle real-world problems with a large number of qubits remains a formidable task. Companies like IBM, Google, and Microsoft are investing in developing quantum processors with increasing qubit counts. However, challenges related to qubit connectivity, error rates, and physical constraints need to be overcome to achieve scalable and practical quantum systems.
