The future of quantum computing lies in modular designs, moving beyond the limitations of a single quantum chip. Researchers have traditionally focused on increasing the number of qubits on a single chip, but this approach has its constraints. A modular approach allows for the integration of multiple quantum chips, enabling the creation of more complex and powerful quantum systems. This shift in design philosophy is driven by the need for greater scalability and flexibility in quantum computing. As quantum technology advances, the urgency to migrate to post-quantum cryptography (PQC) increases, with developments from companies like ARM narrowing the timeline1. The modular design will play a crucial role in the development of practical quantum computers, making it essential for practitioners to consider this approach in their quantum computing strategies. This matters to quantum computing practitioners because it signals a significant change in the way quantum systems will be designed and built, requiring a reevaluation of their current approaches.
